Someone help please. For brainliest answer!!

because they are attracted by the smell of resin/ amber. they become trapped in the substance and the amber hardens

the insects are attracted to the polysaccharide rich thick resin that seeps from the trees. This resin is highly nutritious but has one problem for the insects- its complete lack of viscosity. The thick resin entraps the insects at the bark, and the tree continues to grow outward and in doing so, fossilises the insect alive.

i think that d. wind is the answer.   i missed the question when i answered a. currents.
