Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.818\% 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, or d without using any additional words.
Options:
a: COc1cc(C2NC(=O)NC(c3ccccc3)=C2C(C)=O)ccc1OCC#N
b: O=C(COc1ccc([N+](=O)[O-])cc1)NNC(=O)c1cccnc1
c: CCOC(=O)N1CCN(C(=S)NC2CCCCC2)CC1
d: CCOC(=O)c1c(OCCO)noc1N
Answer: a. COc1cc(C2NC(=O)NC(c3ccccc3)=C2C(C)=O)ccc1OCC#N
