Suggest that patient came himself , able to tell himself of irritability and distraction

Presents to OPD ( suggest that patient came himself , able to tell himself of irritability and distraction - rule out severity because irrespective of duration if symptoms are severe enough ( brought by family members) we label it as manic episode ), duration 5 days again in favour of hypomania

So c looks like answer here

Hypomania (more than 4days symptoms)

It would have been mania if more than 1week symptoms
