Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -4.854% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Fc1cccc(CCN2C(=S)NC[C@@H]2c2ccccc2)c1
[b] CC1=C(C(=O)N(C)CCC#N)C2(CCCCC2)OC1=O
[c] Cc1ccc(C)c2[nH]c(=O)c(CCNC(=O)C(C)(C)C)cc12
Answer: b. CC1=C(C(=O)N(C)CCC#N)C2(CCCCC2)OC1=O
