Task: Answer the multiple-choice question.
Query: Which drug exhibits a -4.520% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCCc1ncc(C(O)(c2ccccc2)c2ccc(C)cc2)n1C
b: COC(=O)c1c(C)[nH]c(C(=O)CN2C(=O)NC3(CCOc4ccccc43)C2=O)c1C
c: COc1ccc(NC(=O)C(CC(C)C)NC(=O)C2CCCCC2)c(OC)c1
d: O=C(NCc1ccc2c(c1)OCO2)C1Cc2ccccc2CN1C(=O)c1ccco1
e: O=C(Nc1ccccc1O)c1cccc(S(=O)(=O)N2CCOCC2)c1
Answer: b. COC(=O)c1c(C)[nH]c(C(=O)CN2C(=O)NC3(CCOc4ccccc43)C2=O)c1C
