Task: Answer the multiple choice question.
Query: Which drug exhibits a -4.053\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) COC(=O)C1=C(C)NC(=O)CC1c1cccc(OC)c1OC
(b) Cc1nc2scc(-c3cccs3)c2c(=O)o1
(c) CC(=O)c1cccc(NC(=O)c2ccc(C)c(S(=O)(=O)N3CCOCC3)c2)c1
(d) Cc1ccc(C(=O)Nc2cccc(-c3nc4ncccc4o3)c2)cc1
(e) COCCn1c(-c2ccc(C#N)cc2)nc2c1c(=O)[nH]c(=O)n2Cc1ccccc1
Answer: a. COC(=O)C1=C(C)NC(=O)CC1c1cccc(OC)c1OC
