Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.026\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) O=C1NC(=O)C(c2ccccc2)(c2ccc(O)cc2)N1
b.) Cc1ccc(OCCNC(=O)c2cccc(Oc3ccc(C(F)(F)F)cc3[N+](=O)[O-])c2)cc1
c.) CCOc1ccccc1N1CCN(C(=O)c2cc3c(C)cc(C)cc3[nH]2)CC1
d.) O=C(CNC(=O)c1ccco1)NCC1CCCO1
Answer: d. O=C(CNC(=O)c1ccco1)NCC1CCCO1
