Task: Answer the multiple-choice question.
Query: Which drug has a -10.455\% 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. N#Cc1ccccc1/C=N/Nc1nc(-c2ccccc2)c2cc(Br)ccc2n1
b. O=C(CNS(=O)(=O)Cc1ccccc1)NCc1ccccc1
c. COc1ccc(-c2noc(CN(C)S(=O)(=O)c3ccc(C)cc3)n2)cc1
d. O=C(Nc1ccc2ccccc2n1)Nc1cccs1
Answer: a. N#Cc1ccccc1/C=N/Nc1nc(-c2ccccc2)c2cc(Br)ccc2n1
