Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.396\% 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, c, or d without using any additional words.
Options:
a. O=C(NCc1ccccc1Cl)c1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1
b. CCN(CC)C(=O)CN1CCN(c2ncccn2)CC1.O=C(O)C(=O)O
c. NC(=O)c1ccsc1NC(=O)CS(=O)(=O)c1ccc(Cl)cc1
d. O=C(Nc1cccnc1Cl)c1cc(-c2ccccc2O)on1
Answer: a. O=C(NCc1ccccc1Cl)c1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1
