Task: Answer the multiple choice question.
Query: Which drug has a 12.971\% 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, b, or c without using any additional words.
Options:
a COc1cc2sc(C)nc2c2ccccc12
b Cc1nn2c(NC(C)C)c3c(nc2c1-c1ccccc1)CCC3
