    Yes the answer should be E . 1. sum of two legs =15 It carries various possibilities like 10 +5 ,9+6,8+7 etc. hence it is not sufficient. 2.Hypotenuse is 12. It does not tell anything about length of base & Perpendicular or other two legs. Not sufficient.

    1+2 also not sufficient .

    H2 = sqr(12) = 144 Now if we try to figure out with 15 . then sqr(10) + sqr(5) = 100+25=125 not matching 144 sqr(11) + sqr(4) = 121 +16 =137 not matching 144 thus it is not possible to figure out easily what are distinct lengths of other two legs.

    Hence C not correct. D is obviously not correct. Ans is E .
