Question

Biologicals are tested in

• A. Mumbai
• B. Kolkatta
• C. Chennai
• D. Kasauli

Hint:

The Central Drugs Laboratory in Kasauli is the designated testing center for biological products in India.

Answer 1

The Correct Option is D

Step 1: Understanding biological testing.
Biologicals, such as vaccines, are tested in designated testing centers. In India, the Central Drugs Laboratory located in Kasauli is responsible for testing biological products for safety, efficacy, and quality.
Step 2: Analyzing the options.
(1) Mumbai: Incorrect, Mumbai does not host the primary testing center for biologicals.
(2) Kolkatta: Incorrect, Kolkatta is not the center for testing biologicals.
(3) Chennai: Incorrect, biological testing is not carried out in Chennai.
(4) Kasauli: Correct — Kasauli houses the Central Drugs Laboratory, where biologicals are tested.
Step 3: Conclusion.
The correct answer is (4) Kasauli.

Answer 2

The question asks which city hosts the designated testing facility for biological products (like vaccines and sera) in India. Rather than recalling the answer directly, let's reason from what we know about India's drug-testing infrastructure and eliminate cities that are known for other regulatory functions.

1. Mumbai: Mumbai hosts various drug regulatory and licensing offices and is an important commercial hub for the pharmaceutical industry, but it is not the site of India's premier biologicals-testing laboratory.
2. Kolkatta: Kolkata has various drug-related institutions, but it is not associated with the specialised national testing of biological products.
3. Chennai: Chennai is a major pharmaceutical manufacturing and export centre, but again it does not house the country's central biologicals testing laboratory.
4. Kasauli: Kasauli, in Himachal Pradesh, is home to the Central Research Institute and the associated Central Drugs Laboratory, which historically has been India's principal government facility for testing and certifying biological products such as vaccines and sera for safety, potency and quality before release.

Since only Kasauli is specifically tied to the historic national biologicals-testing facility, while the other cities are pharmaceutical or commercial centres without that specific role, Kasauli stands out as the answer.

Therefore, the correct answer is Kasauli.
