Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -8.758\% 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] COC(CNC(=O)C1CCCN1C(=O)OCc1ccccc1)OC
[b] O=C1CN2NC(=S)N(c3ccccc3)C2=CN1c1ccc(Cl)cc1
[c] Cc1onc(-c2ccc(Cl)cc2Cl)c1-c1csc(COc2ccccc2)n1
[d] COc1ccc(-c2nnn(CC(=O)N(Cc3ccc(F)cc3)C(C(=O)NC3CCCC3)c3ccc(F)cc3)n2)cc1
Answer: a. COC(CNC(=O)C1CCCN1C(=O)OCc1ccccc1)OC
