Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.584\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. Cc1occc1C(=O)N/N=C/C1=C(N2CCOCC2)/C(=C\c2ccc(Cl)cc2Cl)CC1
b. O=C(CSc1nnc(-c2ccccc2)c(-c2ccccc2)n1)N1CCc2ccccc21
Answer: b. O=C(CSc1nnc(-c2ccccc2)c(-c2ccccc2)n1)N1CCc2ccccc21
