Concept:
A mirror along the \(Y\!-\!Y'\) axis represents a vertical mirror.
In a vertical mirror image:
The order of letters is reversed (right-to-left),
Each letter is laterally inverted.
Step-by-step analysis:
The original word is ALTITUDE.
Reversing the order of letters gives: EDUTITLA.
Each letter must also appear as its left–right mirror image.
Among the given options, only Option (A) shows:
Correct reversed order of letters, and
Proper lateral (left–right) mirroring of each letter.
Conclusion:
Therefore, the correct mirror image of the word ALTITUDE along the \(Y\!-\!Y'\) axis is Option (A).
Final Answer: \(\boxed{\text{Option 1}}\)
