Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.826\% 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. O=C(Nc1ccc(-c2nc3ccccc3o2)cc1)c1ccc2c(c1)OCO2
b. CCCN(CCC)CCCNC(=S)Nc1ccc2nc(N3CCN(C)CC3)cc(C)c2c1
c. CN(C)S(=O)(=O)c1ccc(-c2cn3ccccc3n2)cc1
Answer: a. O=C(Nc1ccc(-c2nc3ccccc3o2)cc1)c1ccc2c(c1)OCO2
