Answer 1

I believe the answer is B

Answer 2

A. After the study of lizards, the naturalist planned to travel to remote lizard habitats.

Step-by-step explanation:

In this case, after the study of lizards, the speaker planned something. What he planned is modified by another verb. He planned "to travel to remote lizard habitats."

So, in this case, we have an infinitive phrase where "to travel" is modifying the verb "to plan."
