The given sentence is intransitive and does not have a direct subject because the horses did not do anything specific. Therefore, options (1a) and (2C) are the correct answers.
Why are the sentences known as intransitive?
An intransitive verb is one that lacks a direct object in its context in grammar. Intransitive verbs are distinct from transitive verbs, which include one or more objects, due to their absence of transitivity.
An object cannot be taken by an intransitive verb. An improper sentence will be produced if an object is used right after an intransitive verb.
However, there might be additional details following the verb, such as a prepositional phrase or an adverb. A verb that doesn't take a direct object is said to be intransitive.
In other words, nothing or anyone is harmed in the process. It just has to do with the subject. A transitive verb is the opposite of an intransitive verb.
