Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.255\% 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=c1[nH]c2ccccc2c(=O)n1-c1ccc(Cl)cc1Cl
b) Cc1ccc(S(=O)(=O)N2CCN(C(=S)NCCc3ccccc3)CC2)cc1
c) CC(C)(C)C1CCC2(CC1)C(Nc1cccc(C(F)(F)F)c1)=NC(=S)N2CC#N
Answer: a. O=c1[nH]c2ccccc2c(=O)n1-c1ccc(Cl)cc1Cl
