I didn't vote because you left the key element off - a photo - which would make any of the options perfectly valid.
What you have to bear in mind is that you are addressing people who know you and accept you in one gender identity and you're telling them that you're actually the other gender.
You're usually at the very start of your transition.
Passing and how you look is very important at this stage. If you've spent any time on these message boards you will notice the 'vanity' threads, 'Do I look female?', 'Could I pass one day?'
Without a photo or a visual representation of what you look like you are inviting who you tell to use their imagination.
This rarely, if ever, works in your favour.
If someone is important enough that you feel you ought to tell them, then I feel you owe it to yourself to make an effort on the presentation.
You don't have to pass (just in case you think you do). I didn't pass when I came out, but a photo made a difference and I feel influenced some people's decision to accept me as me. It gave them a visual representation and a basic idea of what I looked like in my new gender role.
This is what it's about, giving people that new image and basis for their imagination.
Whatever you decide I wish you luck.
