Task: Answer the multiple choice question.
Question: Which compound has a 0.257\% 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 other words.
Options:
(a) CSCC[C@H](NC(=O)NCc1ccc(F)cc1)C(=O)O
(b) CCn1c(SCc2nc3ccccc3[nH]2)nnc1-c1ccncc1
(c) CCCS(=O)(=O)c1c(S(=O)(=O)CCC)c2ccc(C(C)=O)cn2c1C(=O)OC
Answer: a. CSCC[C@H](NC(=O)NCc1ccc(F)cc1)C(=O)O
