Task: Answer the multiple choice question.
Question: Which drug has a 15.250\% 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.) O=C1c2ccccc2C(=O)N1CCc1nn[nH]n1
b.) CCOC(=O)c1[nH]c2cc3c(cc2c1NC(=O)CN1CCN(CCO)CC1)OCO3
