Task: Answer the multiple choice question.
Query: Which drug has a -11.423% 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.) O=c1c2c(-c3cccs3)csc2ncn1-c1ccc(Br)cc1
b.) N#Cc1ccc(NC(=O)COC(=O)C2=COCCO2)cc1
Answer: a. O=c1c2c(-c3cccs3)csc2ncn1-c1ccc(Br)cc1
