answer is D.
HIV is a virus, not a bacteria. HIV does not have cell surface membrane, no ribosomes and does not respire.
Then, is HIV virus considered as a living thing???
because if it doesn't respire, it doesn't have one of the 7 characteristics of life

i assume its varient 12...so..
1 divison of eyepiece=0.2/100= 0.002mm= 2micrometer..
(16-6) division has been increased which means 10 divison and therefore 20 micrometer for 4 hours.. thereofre 5micrometer for a hour!..therefore answer is A
