Am I ready for naturalization and Form N-400?

[cefecha]

I was granted an asylum in August 2002. My green card states: "Resident since 11/21/06" and "Card expires: 11/21/17".
When can I apply for Naturalization?
Also I noticed that on Form N-400 (application for naturalization) on Part 2, there is not check box for "asylee". Which check box should I mark?

You became eligible to apply for a greencard one year after the grant of asylum. You obviously waited longer. At the time of approval of the greencard, it will have been backdated by one year so, the date on the card should be correct according to those rules.

Add 4 years and 9 months to the resident since date on the card. You are a lawful permanent resident (LPR) applying based on 5 years as an LPR under INA 316(a) and pursuant to INA 334(a), if otherwise eligible. You can mail your N-400 on or after 8/22/2011. Read the ton of information available on the www.uscis.gov website about naturalization.

Up to 90 days before you have accumulated 5 years of continuous residence as a LPR.

You would select box A as you're applying under 5 year rule.
