Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.555\% 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] O=C(c1ccc(Cl)cc1)N1CCN(C(=O)C2CCCCC2)CC1
[b] COCCN1CN(S(=O)(=O)c2ccc(Cl)cc2)c2nc3ccccc3nc21
[c] COc1ccccc1NS(=O)(=O)c1cccc(C(=O)NCC(c2ccccc2OC)N2CCCC2)c1
Answer: a. O=C(c1ccc(Cl)cc1)N1CCN(C(=O)C2CCCCC2)CC1
