Task: Answer the MCQ question.
Question: Which compound exhibits a 8.691\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COC(=O)/C(NC(C)=O)=C(\C)c1ccc(Cl)cc1
(b) Cc1ccc(C(=O)Cn2nnc3c(sc4nc5c(c(-c6ccccc6)c43)CCC5)c2=O)cc1
(c) CC(C)c1nnc(NC(=O)c2cnccn2)s1
Answer: a. COC(=O)/C(NC(C)=O)=C(\C)c1ccc(Cl)cc1
