Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.999\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COC(=O)c1ccccc1C(=O)N1CCC(CCC(=O)NC2CC2)CC1
b: O=C(N[C@H]1C[C@@H]1NC(=O)OCc1ccccc1)OCc1ccccc1
c: O=c1[nH]c(C2CCN(S(=O)(=O)Cc3ccccc3)CC2)nc2c1nnn2Cc1cccc(Cl)c1
d: Cc1nonc1C(=O)N/N=C/c1ccc(O)cc1
e: COc1ccccc1CNC(=O)C(=O)NCC1OCCN1S(=O)(=O)c1ccccc1
Answer: c. O=c1[nH]c(C2CCN(S(=O)(=O)Cc3ccccc3)CC2)nc2c1nnn2Cc1cccc(Cl)c1
