Answer:
The correct answer is ésta.
Explanation:
We use a pronoun to refer to a subject without naming it directly.
When we use a demonstrative pronoun what we do is indicate where something or someone is with respect to the speaker.
The demonstrative pronouns in Spanish are as follows:
Éste – ésta – éstos – éstas.
Ése – ésa – ésos – ésas.
Aquél – Aquélla – aquéllos – aquéllas.
