Task: Answer the multiple-choice question.
Question: Which drug exhibits a -4.448% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CCOC(=O)/C(C#N)=C/c1cc(C)n(-c2ccc(Br)cc2)c1C
b O=C(CSc1ncc(-c2ccccc2)[nH]1)Nc1cccc(O)c1
Answer: b. O=C(CSc1ncc(-c2ccccc2)[nH]1)Nc1cccc(O)c1
