An Appendix 2A is a document that must be submitted to the ASX for release to the market.
In this case - the Appendix is being released "as a result of options being exercised or other +convertible securities being converted" (Question 2.1)
You can see the number being exercised in question 2.2c 1 (1 million at a price of $0.10) meaning the person who owns the options has payed 1 million x the exercise price and converted these options to full shares or $100,000.
