The dashed mirror line is vertical, on the right of the word, so the mirror image is the word turned left to right: the order of letters is reversed and every letter is laterally inverted.
The mirror line is vertical and lies to the right of the word ARCHITECTURE, so the image is a lateral (left-right) inversion. In the image the last letter E comes first, then R, U, T, C, E, T, I, H, C, R and finally A, and each letter is itself turned back to front. The correct image therefore reads, from left to right: reversed E, reversed R, U, T, reversed C, reversed E, T, I, H, reversed C, reversed R, A. Option (1) keeps the first part ARCHIT in its normal orientation and only the rest is inverted, so it is not a mirror image. Options (3) and (4) have the E after the first T written the wrong way round (and option (3) also leaves the final E and the R inconsistent), so they are not true mirror images. Option (2) is the only one that, when flipped back, gives exactly ARCHITECTURE. Answer: (2)
