Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.425\% 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 additional words.
Options:
a Fc1ccc(/C=N/Nc2cc(N3CCOCC3)ncn2)cc1
b CC(OC(=O)c1cc2c(s1)CCCCC2)C(=O)NC(N)=O
c Cc1ccccc1N/C=C/C(=C(C#N)C#N)N(C)C
d O=C(NCc1ccc2c(c1)OCO2)C1CCCN(S(=O)(=O)c2cccs2)C1
Answer: b. CC(OC(=O)c1cc2c(s1)CCCCC2)C(=O)NC(N)=O
