Best answer
Right choice is (b) False

To explain I would say: Microfiltration cannot be used to remove viruses as a microfiltration filter has a pore size around 0.1 micron, so when water undergoes microfiltration, many microorganisms are removed, but viruses remain in the water. Ultra filtration would remove these larger particles, and may remove some viruses.
