Problem statement: Answer the multiple-choice question.
Question: Which drug has a 7.281\% 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(CCCC(=O)Nc1ccccc1Br)N/N=C/c1c(F)cccc1Cl
(b) COc1ccc(S(=O)(=O)N2CCC(C(=O)N3CCc4ccccc4C3)CC2)cc1Cl
(c) COc1ccc(NC(=O)c2cc(S(=O)(=O)N3CCCCC3)c[nH]2)cc1Cl
Answer: a. O=C(CCCC(=O)Nc1ccccc1Br)N/N=C/c1c(F)cccc1Cl
