Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.449% 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. CC(C)c1nnc(NC(=O)c2cc3cc(Br)ccc3oc2=O)s1
b. O=C(COc1c(Cl)cc(Cl)cc1Cl)c1ccc(Cl)cc1
Answer: a. CC(C)c1nnc(NC(=O)c2cc3cc(Br)ccc3oc2=O)s1
