On 27th July, 2020 Prime Minister of India virtually inaugurated three new Indian Council of Medical Research (ICMR) high-end testing laboratories tor COVID-19 test at which of the following places?

The correct answer is B) Kolkata, Noida, Mumbai. On 27 July 2020, the PM virtually inaugurated three high-throughput COVID-19 testing labs of the Indian Council of Medical Research (ICMR), located at these three cities, to scale up RT-PCR testing capacity during the pandemic.

Why the others fail:

• A includes Chennai, which was not among the three inaugurated labs.
• C includes New Delhi. ICMR's headquarters is in Delhi, but the headquarters is not one of the newly inaugurated labs. Candidates often mix up the HQ with the new labs.
• D includes Chennai and Delhi, so it is wrong for the same reasons.

Core concept: ICMR is the apex body for biomedical research under the Health Ministry, and during COVID it expanded diagnostic capacity through a network of labs. For Mains, this links to pandemic preparedness, public health infrastructure, and the role of central research institutions in health governance.

Trap: Noida is in the NCR, so aspirants often treat it as Delhi and pick option C. Read the location exactly as given in the PIB release and do not assume it is the same as the capital.
