Task: Answer the multiple choice question.
Query: Which drug has a 2.112\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CSC1=N/C(=C\c2ccccc2F)C(=O)S1
b) Cc1ccc(/C=N/n2cnnc2)s1
