Task: Answer the multiple choice question.
Query: Which compound has a 12.421\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(CSc1ccc(-c2ccc(Br)cc2)nn1)NC1CCCC1
b CCN(C(=O)CSc1nc(N)cc(N)n1)C1CCS(=O)(=O)C1
c CC1=NN(c2ccccc2)C(=O)/C1=C/c1cc2cc(C)ccc2nc1N1CCCCC1
Answer: a. O=C(CSc1ccc(-c2ccc(Br)cc2)nn1)NC1CCCC1
