Task: Answer the multiple choice question.
Query: Which drug has a -2.475\% 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 O=C1Nc2cc(C(=O)N3CCc4ccccc4C3)ccc2S/C1=C\c1ccccc1
b COc1ccc(-n2c(=S)[nH]c3cc(C(=O)Nc4ccccc4OC)ccc3c2=O)c(OC)c1
Answer: a. O=C1Nc2cc(C(=O)N3CCc4ccccc4C3)ccc2S/C1=C\c1ccccc1
