Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.172\% 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] O=C(Nn1cnnc1)c1ccccc1-c1ccccc1
[b] CCOC(=O)n1c(SCC(=O)N(CC)CC)nc2ccccc21
[c] NC(=O)c1ccc(NC(=O)CSc2nnc(-c3ccc4c(c3)OCO4)o2)cc1
[d] CSc1ccccc1OCc1cc(C(=O)N2CCc3sccc3C2)no1
Answer: a. O=C(Nn1cnnc1)c1ccccc1-c1ccccc1
