Task: Answer the multiple-choice question.
Query: Which compound has a 19.720\% 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 other words.
Options:
a) COC(=O)CCCC1=CC2=C(c3ccccc3)C(=O)C(C)(OC(=O)C3CCCC3)C(=O)C2=CN1CCCCO
b) CCOC(=O)CC1C(=O)NCCN1C1CCCC1
c) CCOC(=O)c1ccc(NC(=O)CSc2nc(C)cc(=O)[nH]2)cc1
Answer: a. COC(=O)CCCC1=CC2=C(c3ccccc3)C(=O)C(C)(OC(=O)C3CCCC3)C(=O)C2=CN1CCCCO
