Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 10.143\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cc1cc(NN)nc(Cc2ccccc2)n1
b: O=C(NC(=O)c1ccccc1)Nc1ccc(-c2cnco2)cc1
c: O=C(Nc1ccc(C(=O)O)cc1)/C(=C/c1ccc2c(c1)OCO2)NC(=O)c1cccc(Br)c1
Answer: a. Cc1cc(NN)nc(Cc2ccccc2)n1
