Metallic character decreases on moving from left to right across a period. So, sodium (Na) is more metallic than aluminium (Al).
Also, metallic character increases on moving down the group. Thus, potassium (K) is more metallic than sodium ( Na ).

So, the correct order of the metallic character is
K>Na>Al>Be
