Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.780\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1cccc(C2C(C(=O)c3cc4cccc(OC)c4o3)=C(O)C(=O)N2c2cc(C)on2)c1OC
b COc1ccc(C2CC(c3cccs3)=NN2C(=O)COC(=O)C2CCCCC2)cc1OC
c O=C(CSc1ncccn1)Nc1ccc2[nH]c(=O)[nH]c2c1
d CCCn1nc2cc(C(=O)NCc3ccc4c(c3)OCO4)ccc2c1OCC
Answer: a. COc1cccc(C2C(C(=O)c3cc4cccc(OC)c4o3)=C(O)C(=O)N2c2cc(C)on2)c1OC
