Lets take this step by step
2nd orbit has ‘s’ and ‘p’ subshells only
Subshell s has 1 orbital and subshell p has 3 orbitals
In total there will be 4 orbitals
In question there are 3 electrons in each orbital so total electrons will be 4×3=12
In a period as we go from left to right atomic no. increases i.e no. of electrons increases by 1. So for each electron 1 element is there so if there are 12 electrons; it means there are 12 elements in 2nd orbit.
