Task: Answer the multiple-choice question.
Query: Which compound exhibits a 2.851\% 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 additional words.
Options:
(a) C(\CCc1ccccc1)=N/Nc1nc2ccccc2[nH]1
(b) Cc1nn(CC(=O)Nc2ccc(S(N)(=O)=O)cc2)c(=O)c2ccccc12
(c) CCCCN(C(C)=O)c1c(N)n(CCC)c(=O)n(CC(=O)Nc2cc(Cl)cc(Cl)c2)c1=O
Answer: a. C(\CCc1ccccc1)=N/Nc1nc2ccccc2[nH]1
