Question

Beryllium and aluminium exhibit many properties which are similar. But the two elements differ in (A) forming polymeric hydrides (B) forming covalent halides (C) exhibiting maximum covalency in compounds (D) exhibiting amphoteric nature in their oxides.

Be [Z = 4] has maximum covalency of 4 while Al [Z = 13] has maximum covalency of 6. In rest other properties they behave similarly due to diagonal relationship.
