Of course, that is money earned by you and it has to be shown. Profits or losses incurred on call options and put options are normally shown under the head of business income.
Even if you are not in a taxable income bracket, it is mandatory to show the profits and losses on options trading in your tax returns. Also select the appropriate return form in such cases. 
If the IT department realizes this; and it very easy due to PAN, they can put a very heavy penalty on you. 
Remember that options are treated as securities for the purpose of Income Tax and hence they are not treated as speculative trades. There is one more angle to it. If you have losses and don’t show then you can claim the tax credit for the same.
 Also make it a point to file your returns on time to ensure that you don’t lose the tax gains.
