Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.381% human ether-à-go-go related gene (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 O=C(COc1ccc2ccccc2c1)Nc1ccc(Cc2ccncc2)cc1
b COc1ccc(S(=O)(=O)NCc2cccnc2)cc1NC(=O)c1ccc(C)cc1
c O=C(NNc1nc(-c2ccccc2)c2cc(Br)ccc2n1)c1ccc(S(=O)(=O)N2CCOCC2)cc1
d CCOC(=O)C1CCN(C(=O)/C=C/c2cc(OC)c(OC)c(OC)c2)CC1
Answer: d. CCOC(=O)C1CCN(C(=O)/C=C/c2cc(OC)c(OC)c(OC)c2)CC1
