Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -8.838\% 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] O=C(c1cccs1)N1CCN(C23CC4CC(CC(C4)C2)C3)CC1
[b] CC(C)CCNC(=O)C1(c2cccs2)CCOCC1
[c] O=C(CN(C(=O)c1csnn1)c1cccc(Cl)c1)NCCc1ccccc1
[d] O=C(NC(Cc1ccccc1)C(=O)NCCc1ccccn1)c1ccccc1
[e] O=C(Cn1c(=O)n(Cc2ccc3c(c2)OCO3)c(=O)c2ccccc21)N1CCCc2ccccc21
Answer: a. O=C(c1cccs1)N1CCN(C23CC4CC(CC(C4)C2)C3)CC1
