Task: Answer the multiple-choice question.
Query: Which drug exhibits a -11.341\% 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 CCCCN(C)Cc1c(C)[nH]c2c(Cl)cccc2c1=O
b CC(=O)Nc1ccc(/C(C)=N/NC(=O)CN(c2ccccc2Br)S(C)(=O)=O)cc1
c CCOC(=O)c1c(S(=O)(=O)NCC(=O)N2CCN(c3ccc(F)cc3)CC2)c(C)n(C)c1C
d COc1ccc(NC(=O)C2=C3SCC(=O)N3C(N)=C(C#N)C2c2ccc(Cl)cc2)cc1
Answer: a. CCCCN(C)Cc1c(C)[nH]c2c(Cl)cccc2c1=O
