Part of the passage:

To see how this works, Gordon and her team captured patroller
ants as they left a nest one morning. After waiting half an houri ithey simulated the ants
return by dropping glass beads into the nest entrance at regular intervals – some coated
with patroller scent
, some with maintenance worker scent, some with no scent. Only the
beads coated with patroller scent stimulated foragers to leave the nest.

(B) is wrong because the researchers did not use food;
(C) is wrong because they captured the patrollers ants, they didn’t follow them;
(D) is wrong because they added different scents to beads, not to the ants.
