I believe the correct response is A. The population of secondary consumers would decrease, as now these organisms can't obtain energy through the food they consume which is the primary consumers as there is none and thus the population in higher tropic level dependent on them would decrease. This is the secondary consumer.

The populations of secondary consumers would decrease in an ecosystem without herbivore.

Further Explanation:

In food chain series of organism eat each other to transfer energy from one another. The food chain is started from primary producers and move upward.

In the food chain, primary producers are autotrophs. Organisms that are autotrophs in nature can make their own food. Mainly plants are referred as autotrophs but there are other examples of autotrophs are also present. They use sunlight to make sugar, which then converts into energy. They make their food by photosynthesis. Photosynthetic organisms are mainly green because they contain a chlorophyll pigment which helps in absorbing light.

Primary producers eat by primary consumers that are mainly herbivores and eat plants. Heterotrophs also referred as herbivores that mainly eat plants. The number herbivores are less in ecosystem than autotrophs because they get only ten percent of energy from autotrophs. Some examples of heterotrophs are animal and fungi. Primary consumers eat by secondary consumers in the food chain. They are mainly meat-eaters. Thus, the numbers of herbivores are less in an ecosystem than they affect the population of secondary consumer. This condition occurs due to the dependence of secondary consumers on herbivores which are primary consumers.
