Answer: (A)
Statement 1 is correct: Quantum dots (QDs) are tiny semiconductor nanocrystals. Due to quantum confinement, they absorb light and emit bright, highly stable, and specific light (fluorescence) when excited, typically by UV or blue
light.
Statement 2 is correct: A unique property of quantum dots is that their emission color (wavelength) is directly dependent on their size. By precisely controlling the size of the nanoparticle during synthesis, researchers can "tune" the emission to a specific color, making them excellent for multiplexed optical sensing.
Statement 3 is incorrect: Quantum dots are highly versatile. Their surface can be functionalized (chemically modified) to couple with natural biomolecules such as antibodies, enzymes, and DNA. This ability to act as a fluorescent tag attached to a biological "probe" is exactly what makes them powerful tools in advanced biosensing and medical imaging.
Therefore, option A is the correct answer.

1. It measures the average change in prices received by producers for goods and
services at the wholesale or factory-gate level.
2. It captures price changes before they reach the retail consumer.

Answer: (C)
Statement 1 is correct: The Producer Price Index (PPI) measures the average change over time in the selling prices received by domestic producers for their output. It tracks these price changes at the point of first commercial transaction—which corresponds to the wholesale, factory-gate, or farm-gate level before any retail distribution or consumer taxes are added.
Statement 2 is correct: Because the PPI measures price changes at the producer level (the starting point of the supply chain), it captures price changes before they reach the retail consumer. Because of this, PPI is widely considered an "early warning system" or a leading indicator of future consumer inflation (CPI).
Therefore, option C is the correct answer.

Answer: (B)
● Statement 1 is Correct: The National Commission for Minorities (NCM) is a statutory body established under the National Commission for Minorities Act, 1992 to safeguard the rights and interests of the notified minority communities.
● Statement 2 is Correct: According to the 2011 Census, the six notified religious minority communities—Muslims, Christians, Sikhs, Buddhists, Jains and Parsis (Zoroastrians)—together constitute about 19.3% of India's population, which is approximately one-fifth of the total population.
● Statement 3 is Incorrect: The provision to Section 3(2) of the National Commission for Minorities Act, 1992 specifically provides that "five Members including the Chairperson shall be from amongst the minority communities." The statement incorrectly dilutes this statutory requirement by stating that "at least half" of the members must belong to minority communities. Since the Commission has seven members, "at least half" would imply four or more members, whereas the Act mandates a minimum of five. Therefore, the statement is not legally accurate.
Therefore, option B is the correct answer.
