Task: Answer the multiple-choice question.
Question: Which compound has a -3.855\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=C(CSc1nnc(SCc2ccccc2)s1)N/N=C/c1c(Cl)cccc1Cl
b. O=C1[C@@H]2Cc3c([nH]c4ccccc34)C(c3ccc(Cl)cc3)N2C(=O)CN1CCO
c. Cc1ccc(CN2CCC(CNC(=O)c3ccc(NC(=O)C4=CSCCO4)cc3)CC2)cc1
d. Cc1ccc(C)c(N2CCN(S(=O)(=O)c3c(C)noc3/C=C/N(C)C)CC2)c1
Answer: a. O=C(CSc1nnc(SCc2ccccc2)s1)N/N=C/c1c(Cl)cccc1Cl
