Step 1: Idea:
Picture the row. There are 12 boys to the right of Vijay, because he is 13th from the right.
Step 2: Count the boys on the other side:
Total boys are 45. Take away the 12 boys on his right and Vijay himself. That leaves 45 - 12 - 1 = 32 boys on his left.
Step 3: Find his place:
If 32 boys stand on his left, Vijay is the next one, so he is 32 + 1 = 33rd from the left.
Step 4: Compare with the options:
Option 2, 33rd, matches this result.
Final Answer:
His position from the left is 33rd.
\[ \boxed{33^{\text{rd}}} \]
