Her debut single "Ghost" has gone number one and remained in the top 10 for two consecutive months. Her 2nd single "Glow" is being released right on the heels of her debut album.

How much will Ella ha album sell?

I haven't followed UK album charts for a while so I'm not certain on what numbers are considered good, but I could see her selling maybe 50-60k first week.

edit: Mess @ those poll options. All of the options from 200k and above are wildly unrealistic for the UK, especially considering it's her debut album and she's only 1 single into it. Ed Sheeran's album did like 160k first week so she's not gonna get any higher than that.

60-70k

Your poll options are just obscene. Anything over 100k is just out of the question.

Currently I would honestly guess about 35k. And that's not harsh, those are Lily Allen numbers by the way. She wont even have an X factor performance boost on release week. Of course I would be happy for her to prove me wrong, it would be nice to see 50k+.
