C/D, which you wrote the same answer.

4x² + 3x + 4

Step-by-step explanation:

The two polynomials are added, so we can remove the brackets:

(x² + 2x + 3) + (3x² + x + 1)

= x² + 2x + 3 + 3x² + x + 1

= x² + 3x² + x + 2x + 1 + 3   <=rearrange by like terms (same variable)

= 4x² + 3x + 4   <=after collecting like terms
