Task: Answer the multiple-choice question.
Question: Which drug exhibits a -47.466% 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 other words.
Options:
[a] COc1ccc(N2CSC3=C(C#N)C(c4ccc(OC)c(OC)c4)CC(=O)N3C2)c(OC)c1
[b] O=C(OCC1OC(n2ncc(=O)[nH]c2=O)C(OC(=O)c2ccccc2)C1OC(=O)c1ccccc1)c1ccccc1
[c] COc1ccccc1NC(=O)/C=C/C(N)=O
[d] CCc1nnc(NC(=O)Cn2nc(-c3ccccc3OC)ccc2=O)s1
Answer: a. COc1ccc(N2CSC3=C(C#N)C(c4ccc(OC)c(OC)c4)CC(=O)N3C2)c(OC)c1
