The answer and the reasoning

B. 3

Mass drug administration is given to all eligible residents in an endemic area irrespective of infection status, including people with chronic disease manifestations. Pregnant women, children under 2 years and seriously ill people are excluded. The grandfather, father and girl are therefore eligible, a total of 3.

Option by option

A. 2
The grandfather with hydrocele and the girl are still eligible, so the count is higher than 2.
B. 3 (correct)
Correct. The pregnant mother and the infant are excluded, leaving three eligible members.
C. 4
The infant under 2 years or the pregnant woman would have to be included for 4, and both are excluded.
D. 5
Five assumes that nobody is excluded.
