Task: Answer the multiple-choice question.
Question: Which drug exhibits a 17.303\% 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 other words.
Options:
a: CCOC(=O)c1c(-c2ccc(C)cc2C)csc1NC(=O)CSc1nnnn1C
b: Cc1[nH]c2ccccc2c1/C=C(\C#N)C(=O)NC(C)c1ccccc1
c: Nc1cc(=O)[nH]c(SCC(=O)N2CCc3ccccc3C2)n1
d: CC(NC(=O)c1ccccc1Br)c1ccc2c(c1)CCCC2
Answer: b. Cc1[nH]c2ccccc2c1/C=C(\C#N)C(=O)NC(C)c1ccccc1
