Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.748\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCn1c(C)cc(C)c(C#N)c1=O
b Cc1cc(=O)[nH]c(SCCCOc2ccc(F)cc2)n1
c CN(C)P(=O)(C(Cl)=C(N1CCCCC1)N1CCCCC1)N(C)C
d Cc1cccc2sc(NC(=O)C3CCCO3)nc12
e Cc1cc(C)c(S(=O)(=O)Cc2ccccc2)c(OC(C)C)n1
Answer: a. CCn1c(C)cc(C)c(C#N)c1=O
