Best answer
Right option is (a) Obligate parasites

For explanation I would say: Viruses are an example of obligate parasites. Viruses can’t perform any of their metabolic activities when they are outside a living host. As soon as they enter a living host they replicate and perform their metabolic activities. Therefore, they are an example of obligate parasites.
