Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.474\% 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] CCNC(=S)SCCOc1ccccc1C
[b] COc1ccc(Br)cc1-c1nc(C)c(C(C)=O)n1O
[c] CC1=CC(C)(C)NC(=S)N1c1cccc2cc(S(=O)(=O)O)ccc12
Answer: c. CC1=CC(C)(C)NC(=S)N1c1cccc2cc(S(=O)(=O)O)ccc12
