Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.340\% 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 additional words.
Options:
a. COc1ccccc1N1CCN(CC(=O)Nc2cccc(F)c2)CC1
b. CN(C)C=O.N#Cc1ccccc1OCC(=O)OCC(=O)c1ccc2c(c1)NC(=O)CO2
c. CCSc1nnc(NC(=O)C(CC)(C(F)(F)F)C(F)(F)F)s1
d. O=C(Nc1ccc2c(c1)OCCO2)c1ccc(Br)o1
Answer: d. O=C(Nc1ccc2c(c1)OCCO2)c1ccc(Br)o1
