The earliest English settlers in Virginia failed to survive

[PriyankaR833]

The earliest English settlers in Virginia failed to survive their first winter in the New World because of
factors such as inadequate food supplies, harsh weather, and an inability to communicate with Native
Americans.
• an inability
• that they were unable
• because they were unable
• being unable
• Lacking an ability

Here, 'being unable' I wish to know what kind of construction is this?
