Task: Answer the multiple-choice question.
Query: Which drug exhibits a -21.087% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COC(=O)/C=C/c1ccccc1CN1[C@@H](CC(=O)OC)c2ccccc2S1(=O)=O
b. Cn1c(=O)[nH]c(=O)c2c1nc(N1CCOCC1)n2CCSc1nnnn1-c1ccccc1
Answer: b. Cn1c(=O)[nH]c(=O)c2c1nc(N1CCOCC1)n2CCSc1nnnn1-c1ccccc1
