I think it is ambiguours que bcoz there is no information given about when wall fall so i that situation we have a choice to consider when walll will fall so i think may be option B is also incorrect.

 

pls correct me if i am wrong

From the statement it can be concluded that wall sometimes breaks irrespective of who sitting when sitting what doing.

Humpty and Dumpty always having their lunch on wall which means they fall sometimes due to wall break.

a)Not true

b)True as wall not breaking all time

c)Not true what if they having dinner on wall and it break too so definitely it make them fall

d)Not true
