Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.381\% 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(CCc1nnc(CCCc2ccccc2)o1)N1CCCCCC1
(b) O=C(O)CCNc1ccc2c(c1)OCCO2
(c) CCN(CC)c1ccc(/C=N/N2CCOCC2)c(O)c1
(d) Cc1c(CN(C)C(=O)c2ccc(Br)o2)cnn1C
(e) COc1ccc(N(C(=O)/C=C/c2ccc(OC)c(OC)c2)C2=CC3CCC(C2)N3C)cc1.Cl
Answer: d. Cc1c(CN(C)C(=O)c2ccc(Br)o2)cnn1C
