Boron form covalent compound due to

Higher ionization energy

Lower ionization energy

Small size

Both $(a)$ and $(c)$

Solution

Boron forms covalent bonds due to small size of boron. Also because of its size the sum of its first three ionization enthalpies is very high. This prevents it to form $+3$ ions and forces it to form only covalent compounds.
