Answer: Choice D
(3+5i) - (2+i)
We can verify this by the following steps
(3+5i) - (2+i)
3+5i - 2 - i .... distribute the negative to all terms in the parenthesis
(3-2) + (5i-i)
1 + 4i
------------
Something like choice C is close, but not quite there
(3+5i) - (2+i)
(3+5i) - (2-i)
3+5i - 2+i
(3-2) + (5i+i)
1 + 6i
Choices A and B aren't a match as well for similar reasons, though they aren't as close as choice C is.
