Question

A ti _____ gustan las plantas

Answer 1

In Spanish, the "like" verb works as shown in these examples (present):

A mi me gustan = I like them.

A ti te gustan = You (singular) like them.

A vosotros os gustan = You (plural) like them.

So:

Ti = you

The personal pronoun that would correctly fit the sentence is "te".

Therefore:

A ti te gustan las plantas = You (singular) like the plants.
