Jawaban:

The correct answer is: a. plays

The clue is in the word "always". Since it refers to Tony's habitual or regular action of playing the violin every afternoon, we use the simple present tense 'plays'.

The other options are incorrect:

b. played - Simple past tense. We don't use it because the sentence refers to Tony's regular, ongoing action.

c. is playing - Present continuous tense. We don't use it because the focus is on Tony's habit, not a temporary action he is doing right now.

d. are playing - Present continuous tense in plural form. This is incorrect because the subject 'Tony' is a single person, not multiple people.

So in summary, the correct answer is:

1. Tony is a very talented child. Every afternoon, he always plays the violin in his bedroom.
