Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.566\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=S(=O)(c1ccc(Br)cc1)N1CCN(c2ccc3nnc(-c4ccccc4)n3n2)CC1
b CCC(C)(C)n1nnnc1C(c1cc2ccc(OC)cc2[nH]c1=O)N1CCc2ccccc2C1
c O=C(NC(=S)Nc1ccccc1N1CCOCC1)c1sc2ccccc2c1Cl
Answer: c. O=C(NC(=S)Nc1ccccc1N1CCOCC1)c1sc2ccccc2c1Cl
