Formation 1 is an intrusion.
Reason: Formation 1 cuts across the bedding of the other rock layers, so it must be magma that forced its way into existing rock and solidified (an intrusive igneous body). The other statements are not necessarily true from the diagram: Formation 2 isn't clearly a surface lava flow (extrusion), the features aren't shown as faults, and you can't assume both are igneous.
