Detailed Solution

The structure of diborane is:

The value of X is $97 °$ and the value of Y is $120 ° .$ The Value of P is 131 pm and the value of q is 119 pm. This implies that statements present in option 1 and option 2 are correct. Boron forms four bonds, two bonds with terminal hydrogens and two with bridge hydrogens. Therefore, boron has sp³ hybridization in B₂H₆. Therefore, the statement present in option 3 is also correct.

The bond length of bridge hydrogens is longer than the terminal hydrogens yet it is stronger because it cannot be replaced during the chemical reactions. Therefore, the statement present in option 4 is wrong.
