Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -43.167% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=C(NCC1CCN(Cc2ccccc2F)CC1)Nc1cccc(Br)c1
b. NC(=O)c1ccc(C(F)(F)F)n(Cc2ccccc2Cl)c1=O
c. COc1ccc(C2C(C(=O)Nc3ccc4c(c3)OCCO4)c3ccccc3C(=O)N2C)cc1
d. Nc1ccccc1Nc1cc(-c2ccc(Cl)cc2)nn1-c1ccccc1
Answer: a. O=C(NCC1CCN(Cc2ccccc2F)CC1)Nc1cccc(Br)c1
