Task: Answer the multiple choice question.
Query: Which compound has a 19.197\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Cn1c(-c2cccs2)[n+](C)c2ccccc21.[Cl-]
[b] CC[C@@]1(c2cccc(C)c2)C(=O)N(C(=O)OC)N1C(=O)OC
[c] CC(C)NC(=O)NC(=O)CSc1ccc(S(=O)(=O)N2CCCC2)cn1
[d] CC(=O)Nc1ccc(Sc2ccccc2C(=O)O)cn1
Answer: b. CC[C@@]1(c2cccc(C)c2)C(=O)N(C(=O)OC)N1C(=O)OC
