$\displaystyle\bullet$ $\alpha = 90^o$ , whereas, $\displaystyle \beta = 109^o28'$ . So, this is incorrect.

$\displaystyle\bullet$ Saturated means only single bonds, while Unsaturated means double bonds as well. So, this is true.

$\displaystyle\bullet$ Double Bond is shorter in length than a single bond, so this is incorrect.

I think even the second option should be wrong..... It's degree of unsaturation is 1

alpha is 90 and thus 1st compound has much bond strain C=C bond length is lesser than C-C due to better overlapping and thus c) is correct!

Since left compound is composed of only single bonds, it is a saturated hydrocarbon. Whereas, the right compond is consisting a double bond, it is an unsaturated hydrocarbon.
