Task: Answer the multiple-choice question.
Query: Which compound has a 21.685% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C(Nc1ccc(NC(=O)N2CCN(c3ccccc3O)CC2)cc1)N1CCN(c2ccccc2O)CC1
b CS/C(N)=N/N=C/c1ccc2c(c1)OCO2
Answer: a. O=C(Nc1ccc(NC(=O)N2CCN(c3ccccc3O)CC2)cc1)N1CCN(c2ccccc2O)CC1
