Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.098\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COc1ccccc1NS(=O)(=O)c1cc(NC(=O)CC(C)(C)C)ccc1N1CCOCC1
b) O=C(NC1=NCCS1)c1ccncc1
c) CN1CCN(C(c2cccc(Cl)c2)c2ccccc2Cl)CC1.O=C(O)/C=C\C(=O)O
d) COc1ccc(C(=O)NCc2nnc(SCC(=O)N3CCCc4ccccc43)o2)cc1OC
Answer: b. O=C(NC1=NCCS1)c1ccncc1
