Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 18.489\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCCCS(=O)(=O)Nc1ccc(N2CCOCC2)c(S(=O)(=O)N2CCOCC2)c1
[b] O=c1oc2cc(O)ccc2c2oc3cc(O)ccc3c12
[c] CC(C(=O)Nc1ccccc1Cl)N(c1ccccc1)S(C)(=O)=O
[d] CC(C)C(=O)Nc1ccc(NC(=O)c2cccs2)cn1
Answer: c. CC(C(=O)Nc1ccccc1Cl)N(c1ccccc1)S(C)(=O)=O
