Territorial insects like spiders that fight off intruders would be expected to be a) regularly distributed b) randomly distributed c) clustered together d) b and c e) selectively distributed

I believe the answer would be B.

A) regularly distributed

Explanation:

Territorial insects such as spiders and ladybugs that fight invaders are expected to be distributed regularly, based on the incidence of invaders. These territorial insects efficiently control crops and facilities, keeping them protected from pest invaders.

It is worth mentioning the insects that parasitize or feed on agricultural pests, as well as pathogens that  cause some kind of disease in insects. The use of certain insects can also happen, which is usually done in two ways:  releasing them in the production area or, in certain situations, allowing insects already operating in the area to increase in number and remain close to crops.
