It happened because of the mistakes in the instructions given in ITR-4 of the assessment year 2013-14. The mistake is in the column 'sector' wherein serial numbers nos 7 to 9 and the respective headings were missed out. I have compared with the corresponding instructions given in ITR4 for the assessment year 2012-13 and reconsider my observation as below.
Beauty parlour comes under 'BUSINESS' hence 44AD can be opted. However code remains the same as 0702.
