Answer:
cuales son los instrumentos?
The sentence is not very clear, I suppose the answer is "presta".
<span>It is better just to translate the sentence so that you will know which options you can omit and on which you have to focus. In English this sentence means 'I want this shirt and not that one'. Now you can easily understand that this task is not about tenses as it is focused on the usage of demonstrative pronouns like 'this (esta)' and 'that(aquella)'. Therefore, the correct answer is: demonstrative pronouns.</span>
