Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.486\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. COc1ccc(/C=C2/C(=O)N=C(N)N2C)cc1OC
b. O=c1[nH]c2cc(Cl)ccc2o1
c. CCC(CC)C(=O)Nc1cc([N+](=O)[O-])ccc1Cl
d. C/C(Nc1ccc(Cl)cc1)=C(/C#N)C(N)=O
Answer: d. C/C(Nc1ccc(Cl)cc1)=C(/C#N)C(N)=O
