respected sir,
1) question no 5 --step 2 is also wrong .
2)question no 3--given that the answer is Length of longest sentence based on number of charecters.I know that letters are charecters, but there are semicolon ,colon etc with some of these words and we are not counting that .Then how can we say that 'based on number of charecters'.It is only based only on number of letters.There is a none of the above option also .
