AVZO options, page-605

Just had a quick look at trades for AVZO this morning, can someone with more of an idea indicate if the following image implies accumulation or distribution, my uninformed interpretation is distribution as the entity is gradually raised the offer getting best price i.e not just dumping.  Not what I personally want to see, as I am, as previously mentioned pretty heavy into AVZO's.  This post is for a learning experience for my future reference, I'm just as bullish on AVZ as I was last week, yesterday and will be until that JV or sale is announced.

Thanks in advance for any feedback.
