The Ishihara test is related with
Detailed Explanation:
The Ishihara test is a widely used medical screening tool designed to detect colour vision deficiency, specifically red-green colour blindness.
It consists of plates with coloured dots that form numbers or patterns visible only to individuals with normal colour vision; those with red-green deficiency fail to identify the hidden figures, making it the standard diagnostic method for colour blindness.
Which class of immunoglobulin is the first to be produced in response to an infection?

Detailed Explanation:
Chloroquine is an antimalarial drug used for treatment and prophylaxis of malaria, making this pair correctly matched.
Tuberculosis is prevented by BCG vaccine (not ATS); Tetanus is prevented by tetanus toxoid (not BCG); Scurvy results from vitamin C deficiency (not thiamine/vitamin B1).
Therefore, only Malaria-Chloroquine is correctly matched, making Option 3 the correct answer.
