Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.759% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) NC(N)=N/N=C/c1ccc(N2CCOCC2)cc1.O=[N+]([O-])O
(b) O=C(NCCN1CCOCC1)c1cc2n(n1)C(C(F)(F)F)CC(c1ccc(F)cc1)N2
(c) O=C(O)c1cccc(Cl)n1
(d) COc1ccc(S(=O)(=O)Nc2cc(C)on2)cc1NC(C)=O
Answer: c. O=C(O)c1cccc(Cl)n1
