Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.839\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. COc1ccc(NC(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)cc1OC
b. O=[N+]([O-])c1ccc(NCCCO)c(C(F)(F)F)c1
c. O=c1c2c(nc3nc(NCc4ccccc4Cl)[nH]n13)CCC2
d. COC(=O)C1=C(C)NC(=O)/C1=C\c1cc(C)n(-c2c(C)cccc2C)c1C
Answer: d. COC(=O)C1=C(C)NC(=O)/C1=C\c1cc(C)n(-c2c(C)cccc2C)c1C
