Task: Answer the multiple-choice question.
Question: Which drug has a 3.299\% 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 additional words.
Options:
a: O=C(NCc1ccncc1)c1cncc(Br)c1
b: COc1ccc(CC(=O)N/N=C/C=C/c2cccc([N+](=O)[O-])c2)cc1OC
c: CC1(C)Cc2nc3sc4c(NCCO)ncnc4c3cc2CS1
d: Cc1c(N=Cc2ccccn2)c(=O)n(-c2ccccc2)n1C
e: CCOC(=O)c1c(NC(=O)CSc2nc3cccnc3n2C)sc(C(C)=O)c1C
Answer: a. O=C(NCc1ccncc1)c1cncc(Br)c1
