Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 5.089\% 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, d, or e without using any other words.
Options:
a COc1ccc2[nH]c3c(NCCCOC(C)C)ncnc3c2c1
b CCCCc1nnc(NC(=O)C23CC4CC(CC(NC(C)=O)(C4)C2)C3)s1
c COc1ccc(C(=O)/C=C/Nc2ccc(C)cn2)cc1OC
d CC1CC(C)CN(Cc2nc(N)nc(Nc3ccccc3)n2)C1
e C=CCn1c(C)cc(C(=O)Cn2nc(C(=O)O)c3ccccc3c2=O)c1C
Answer: e. C=CCn1c(C)cc(C(=O)Cn2nc(C(=O)O)c3ccccc3c2=O)c1C
