Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.777\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CCCCCC(O)CCc1n[nH]c(=S)n1-c1ccccc1
b) COC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCCN3CCOCC3)C2c2ccccn2)c1C
c) COCCN(CC1CCCN(C2Cc3ccccc3C2)C1)C(=O)CCC(N)=O
Answer: b. COC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCCN3CCOCC3)C2c2ccccn2)c1C
