c

1 and 3 only

d

1, 2 and 3

Explanation

Statements 2 and 3 are correct. Statement 1 is incorrect.

Covishield (Oxford-AstraZeneca) relies on a viral vector platform (a modified chimpanzee adenovirus), not an mRNA platform (which is used by Pfizer and Moderna). Sputnik V is also a viral vector vaccine. Covaxin (Bharat Biotech) relies on traditional inactivated virus technology.

Covishield uses an adenovirus vector; it is not an mRNA vaccine.

Answer: (b).
