Task: Answer the multiple choice question.
Question: Which drug exhibits a 23.264\% 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 or b without using any additional words.
Options:
a. C=CCSc1nc2ccccc2[nH]1
b. CCOC(=O)/C=C/CN(C(=O)OC(C)(C)C)S(=O)(=O)N1CC=CC1
Answer: a. C=CCSc1nc2ccccc2[nH]1
