Task: Answer the multiple choice question.
Query: Which drug exhibits a -12.861% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CCNS(=O)(=O)c1c(C)cc(N2CCCC2=O)cc1C
b. Br.CC1(C)OC(c2ccccc2)=C/C(=C/C=Nc2ccccc2)O1
Answer: b. Br.CC1(C)OC(c2ccccc2)=C/C(=C/C=Nc2ccccc2)O1
