Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 9.962\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(N/N=C/C(Br)=C/c1ccccc1)NC1CCCCC1
b: O=C(CSc1nnnn1-c1ccccc1)Nc1nsc(-c2ccc(Cl)cc2)n1
Answer: a. O=C(N/N=C/C(Br)=C/c1ccccc1)NC1CCCCC1
