Task: Answer the multiple-choice question.
Query: Which drug exhibits a 21.646\% 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.) Cc1c(NC2=NC3(CCCCC3)Cc3ccccc32)c(=O)n(-c2ccccc2)n1C
b.) Cn1ncc(-c2ccno2)c1C(=O)O
c.) Cc1nc2ccc(NC(=O)c3cccnc3)cc2s1.O=C(O)C(=O)O
Answer: b. Cn1ncc(-c2ccno2)c1C(=O)O
