Problem statement: Answer the multiple choice question.
Question: Which compound has a 18.545\% 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, or c without using any additional words.
Options:
(a) C/C(=N\NC(N)=O)c1ccc(Cl)s1
(b) CCc1ccc(NC(=O)NCCN2CCc3ccccc3C2)cc1
(c) Cc1csc(C(C)NC(=O)c2ccc(OC3CCN(CCc4ccccc4)CC3)cc2)n1
Answer: a. C/C(=N\NC(N)=O)c1ccc(Cl)s1
