Answer:
Verbal: to catch
Kind: infinitive
Explanation:
The verb to catch is in the full infinitive form - with the preposition to followed by an infinitive form of the verb. In this example, the full infinitive to catch is used to indicate purpose. Thus, the sentence means that he waits at the bus stop in order to catch the bus.
The rest of the options are incorrect because waits is the main verb, at the bus stop is a prepositional phrase, a gerund is a verb with the -ing form and a participle is a word formed from a verb that functions as an adjective or noun.
