Urgetn reg I-485 and H-1B extn

[rmantena]

Hi,

I have worked for Employer A from 2008 - 2011 and joined company B in 05/2011. My previous employer has processed my GC and has approved I-140 with PD 02/2010. so in the month of Mar i have applied for I-485 for Employer A. When i have transfered my H-1B to Employer B in Mar/2011 i got my H-1B approval till May 2012 and now im in the process of applying for my H-1b extn. I have couple of questions:

1) In H-1B extn what happens if i mention as "NO" to question asking for is AOS is applied or not??

2) Do i need to reveal that i have applied for AOS with Emploter A whereas my H-1B extn is for Employer B?

3) Will i get my H-1B extn now??

Thx
