Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.446\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. Nc1ccc(-c2nc3ncccc3o2)cc1
b. Cc1cccc(NC(=O)CSc2nnc(CCC(=O)Nc3ccc(C)c(Cl)c3)n2C)c1
c. O=S(=O)(c1ccc(Cl)cc1)N1CCCN(c2ccc(C(F)(F)F)cn2)CC1
Answer: c. O=S(=O)(c1ccc(Cl)cc1)N1CCCN(c2ccc(C(F)(F)F)cn2)CC1
