To rewrite the English alphabet in the described format, each pair of letters alternates between lowercase and uppercase: ab, Cd, Ef, etc., until reaching the end with yz. Therefore, July would be rendered as jUlY.

Mentally, you can visualize these pairs as transitioning from lowercase to uppercase. In the case of July, ‘y’ is the last letter, so it would be in uppercase (‘Y’). As for ‘j’, it would be in lowercase. Consequently, options (b) and (c) are eliminated since ‘Y’ is uppercase. Furthermore, since ‘j’ is lowercase, option (a) is also eliminated. Thus, the correct answer is option (d).
