Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.681\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(CN1CCN(C(=O)c2ccccc2)CC1)Nc1ccccc1
b: COc1ccc(C(CNC(=O)CCC(=O)c2ccc(C)s2)N2CCOCC2)cc1
c: CCCCCOc1ccc(C2C(C(C)=O)=C(C)Nc3ncnn32)cc1OC
d: COc1ccccc1C1C(C(N)=O)=C(C)Nc2ncnn21
e: C=CCNC(=O)N[C@@H](CCSC)C(=O)OC
Answer: d. COc1ccccc1C1C(C(N)=O)=C(C)Nc2ncnn21
