Answer:

  B.  -2/5+9/15 = 3/15

Step-by-step explanation:

The only two answer choices that have -2/5 as part of the sum are B and C. Of those, choice C incorrectly represents the subtraction of -9/15.

The only reasonable choice is B.

__

The result can be reduced from 3/15 to 1/5 by removing a factor of 3 from numerator and denominator.
