Task: Answer the MCQ question.
Query: Which drug exhibits a 15.236\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] S=C1NC(c2ccccc2)=NCN1c1ccc(Br)cc1
[b] O=C1c2ccccc2C(=O)N1CCCON1C(=O)c2ccccc2C1=O
[c] C[NH+](C)CC(C)(C)CNS(=O)(=O)c1ccc(Cl)c(Cl)c1.[Cl-]
[d] CCn1nc(C)c(NC(=O)/C=C/c2ccc(OC)c(COc3ccc(Br)cc3)c2)c1C
[e] CCOc1ccc(N(CC(=O)NN=C2CCCC2)S(C)(=O)=O)cc1
Answer: a. S=C1NC(c2ccccc2)=NCN1c1ccc(Br)cc1
