Problem statement: Answer the multiple-choice question.
Question: Which drug has a 6.874\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1c(C)cc(Br)cc1C(=O)O
b: O=C(O)C1C2C=CC(O2)C1C(=O)NCc1ccc2c(c1)OCO2
c: C/C(=N\NC(=O)C(N)=O)c1ccc(O)cc1O
d: COc1ccc(-n2c(CN3CCC(C)CC3)nc3ccc([N+](=O)[O-])cc3c2=O)c(OC)c1
e: Cc1cc2ncn(/N=C/c3ccc([N+](=O)[O-])s3)c2cc1C
Answer: a. COc1c(C)cc(Br)cc1C(=O)O
