Question

Most viruses are about _____ times smaler than the average cell.

a 1,000
b 300
c 100
d 10

Answer 1

And viruses are smaller again — they're about a hundredth the size of our cells. So we're about 100,000 times bigger than our cells, a million times bigger than bacteria, and 10 million times bigger than your average virus!

I would put A. 1,000 if that is your only other option

Answer 2

A) 1000

Most viruses are 1000 times smaller than the average cell
