Which of the following is a reasonable explanation for why unsaturated fatty acids help keep any membrane more fluid at lower temperatures?

The double bonds form kinks in the fatty acid tails, forcing adjacent lipids to be further apart.
Unsaturated fatty acids have a higher cholesterol content and therefore more cholesterol in membranes.
Unsaturated fatty acids permit more water in the interior of the membrane.
The double bonds block interaction among the hydrophilic head groups of the lipids.
The double bonds result in shorter fatty acid tails and thinner membranes.
