ANSWER

A. (2x + 3, 2y)

EXPLANATION

Let the original coordinates be (x, y)

First, there was a dilation of scale factor 2.

This means that the coordinates become:

2 * (x, y) => (2x, 2y)

Then, there was a translation of 3 units to the right. That is a translation of 3 units on the horizontal (or x axis).

That is:

(2x + 3, 2y)

So, the answer is option A.
