Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 12.920\% 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 additional words.
Options:
(a) C=CCn1c(CC(=O)OC)csc1=Nc1ccc(C(C)=O)cc1
(b) CCN(CC)C(=S)SC(C)C(=O)c1cc(Br)ccc1O
(c) O=C(CC1NCCNC1=O)Nc1cc(Cl)cc(Cl)c1
(d) CCc1ccc(N2CC(C(=O)Nc3ccc(F)cc3)CC2=O)cc1
(e) Cc1cc(=O)[nH]c(-c2ccccc2OC(F)(F)F)n1
Answer: c. O=C(CC1NCCNC1=O)Nc1cc(Cl)cc(Cl)c1
