Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 2.435\% 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 additional words.
Options:
a CC1=C(C#N)C(c2cccnc2)C2=C(CCCC2=O)N1
b O=C(Nc1nc(-c2ccccc2Cl)cs1)c1cccnc1
c O=C(COC(=O)c1ccc(Cl)cc1O)NC(=O)C1CCCCC1
d O=c1[nH]c2ccccc2n1CCCSc1cnc2ccccc2n1
e CCCSc1nc(SCC(=O)NCc2ccccc2)c2c3c(sc2n1)COC(C)(CC)C3
Answer: a. CC1=C(C#N)C(c2cccnc2)C2=C(CCCC2=O)N1
