Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.947\% human ether-à-go-go related gene (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=C1CCCC/C1=C/NCc1ccc(F)cc1
b) COc1ccc(CN2C(=NC(=O)C3CC3)SC3CS(=O)(=O)CC32)cc1
Answer: a. O=C1CCCC/C1=C/NCc1ccc(F)cc1
