Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 1.439\% 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 additional words.
Options:
[a] CC1C(C#N)=C(N)OC2=C1C(=O)CC(C)(C)C2
[b] Cc1ccc(Cn2ccc(NC(=O)c3cc(-c4ccc(Br)cc4)on3)n2)cc1
[c] Cn1c(N)c(C(=O)CSc2ccc3c(c2)OCCO3)c(=O)n(C)c1=O
[d] N/C(=N\OC(=O)COc1ccc(Br)cc1Cl)c1ccccn1
Answer: a. CC1C(C#N)=C(N)OC2=C1C(=O)CC(C)(C)C2
