Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.099\% 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 C=CCNC(=O)c1snnc1-c1ccccc1
b O=C(NC(=S)Nc1ccccc1N1CCCC1)c1ccccc1[N+](=O)[O-]
c O=C(NCC1CCCO1)C1CCCN(S(=O)(=O)c2cccc(C(F)(F)F)c2)C1
Answer: a. C=CCNC(=O)c1snnc1-c1ccccc1
