    B. - 5a³b-a²b²+4

    Step-by-step explanation:

    -8a³b+3a²b²-5

    2+5a²b²

    3a³b+7-9a²b²

    -8a³b+3a²b²-5+2+5a²b²+3a³b+7-9a²b²=

    -5a³b+3a²b²-5+2+5a²b²+7-9a²b²=

    -5a³b-a²b²-5+2+7=

    -5a³b-a²b²+4

    The option that fits this best is B.

    A. - 5a³b-a²b²+2

    B. - 5a³b-a²b²+4

    C. - 5a³b+8a²b²+4
