Show answer & explanation
Correct answer: B
From Panel I, the required row counts from top to bottom are 3, 1, 2, and 2. The required column counts from left to right are 2, 2, 2, and 2.
Check each option against both sets of counts.
Option (ii) has 3 shaded cells in the first row, 1 in the second row, 2 in the third row, and 2 in the fourth row. Its four columns also each contain exactly 2 shaded cells.
The other options fail at least one row or column count.
Therefore, the correctly shaded grid is option (ii).
