Task: Answer the MCQ question.
Query: Which drug exhibits a -4.126% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COc1cc(-c2nnc(SCC(=O)/C(C#N)=C(\C)N)o2)cc(OC)c1OC
[b] Cc1cc(NC(=O)Nc2ccc(Cl)cc2)n(C(C)(C)C)n1
[c] O=C(OCC(=O)N1CCCCCC1)c1n[nH]c(=O)c2ccccc12
[d] COCCNC(=O)CN(Cc1cccs1)C(=O)CCC(=O)Nc1nccs1
Answer: a. COc1cc(-c2nnc(SCC(=O)/C(C#N)=C(\C)N)o2)cc(OC)c1OC
