Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.668\% 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] O=C(COc1ccccc1-c1ccccc1)NNC(=O)NC1CCCCC1
[b] O=C(Nc1ccccc1C(=O)O)c1ccc2ccccc2n1
[c] COCCn1c(C)cc(C(=O)CSc2ncn[nH]2)c1C
[d] COc1ccc(O)c(C(=O)c2cc(C#N)c(=O)n(-c3c(C)n(C)n(-c4ccccc4)c3=O)c2)c1
[e] CCC(=O)Nc1ccc(F)c(Cl)c1
Answer: a. O=C(COc1ccccc1-c1ccccc1)NNC(=O)NC1CCCCC1
