Task: Answer the multiple-choice question.
Query: Which drug has a 4.080\% 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. COc1cc(-c2[nH]ncc2CN(C)C2CCOC2)cc(OC)c1OC
b. COC(=O)c1cc(C(=O)OC)cc(N2C(=O)CC(NNC(=O)c3ccccc3Br)C2=O)c1
c. CC(C)N1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3ccccc3)C2C1
d. Cc1ccc(NC(=O)CCn2c(=O)[nH]c3ccsc3c2=O)cc1C
Answer: b. COC(=O)c1cc(C(=O)OC)cc(N2C(=O)CC(NNC(=O)c3ccccc3Br)C2=O)c1
