Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -20.729% 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, c, or d without using any additional words.
Options:
a) CCOc1cc(Cl)c(S(=O)(=O)NCc2ccccn2)cc1Cl
b) CCCCN(CC)Cc1c(C)[nH]c2ccccc2c1=O
c) COc1ccc(N/N=C(/C(C)=O)N2CCCc3ccccc32)cc1
d) Cc1cccc(C)c1NC(=O)COC(=O)c1c2c(nc3ccccc13)/C(=C\c1ccc3c(c1)OCO3)CCC2
Answer: b. CCCCN(CC)Cc1c(C)[nH]c2ccccc2c1=O
