Task: Answer the multiple-choice question.
Question: Which compound exhibits a 1.050\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C1NC(=O)N(c2ccccc2)C(=O)/C1=C/C=C/c1ccco1
b: Cc1nc(SCc2ccc(C(=O)O)cc2)nc2c1CCCC2
Answer: a. O=C1NC(=O)N(c2ccccc2)C(=O)/C1=C/C=C/c1ccco1
