Ga-31-Ar-4s23d104p1Al-13-1s22s22p63s23p1Small radius of Ga to poor screening effect of d- f orbital and increase in nuclear charge-

The reason(s) for small radius of $G a$ compared to $A l$ is/are :
poor screening effect of $d$ and $f$ orbitals.
increase in nuclear charge
presence of higher orbital
higher atomic number

$G a (31) = [A r] 4 s^{2} 3 d^{10} 4 p^{1}$
$A l (13) = 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{1}$
Small radius of $G a$ to poor screening effect of d, f orbital and increase in nuclear charge.
