    its A 56.
    i thought it could be B at first, as
    B would be if you consider the three suits and 2 ties, (3*2) which equals 6, 56*6=336. so it would be, how many choices does he have in deciding which 3 suits and 2 ties.. but that doesnt make any sense because they are still the same 7 suits and same 8 ties, so it is A. 56
    its just a weird worded question i think. net

    No, you’re wrong.
    It’s 7C3 * 8C2 = 35 * 28 = 980.
    Maybe it’s C, but that’s a typo.
    The correct answer is 980 wangsacl
