Task: Answer the multiple choice question.
Query: Which compound has a 1.372\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CC(C)NC(=O)CC(=O)N/N=C/c1c(F)cccc1Cl
[b] CC(=O)Nc1ccc(S(=O)(=O)NCCC(=O)NCCCc2ccccc2)cc1
[c] CCc1c(C2(O)CCCCC2)[nH]c2cc(C(=O)OC)ccc12
[d] Cc1c(Cl)cccc1NC(=O)CSc1nc2ncc(Cl)cc2[nH]1
Answer: a. CC(C)NC(=O)CC(=O)N/N=C/c1c(F)cccc1Cl
