Task: Answer the multiple-choice question.
Query: Which drug has a -7.021\% 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 other words.
Options:
(a) O=C(Nc1ccc(Cc2ccncc2)cc1)c1cc(F)c(F)cc1Cl
(b) CCc1nnc(NC(=O)CCC(=O)NC2CCCC2)s1
(c) Cc1cc(N2CCCCC2)nc(N2CCOCC2)n1
(d) COc1ccc(C)cc1S(=O)(=O)N1CCN(C(=O)c2ncoc2-c2cccc(C)c2)CC1
Answer: a. O=C(Nc1ccc(Cc2ccncc2)cc1)c1cc(F)c(F)cc1Cl
