In a certain code ORCHESTRA is written as ARTSEORCH. How is DREAMLAND written in that code. ORESTRA

Look at the given example: ORCHESTRA → ARTSEORCH.

Compare letters by position (original → code):

O R C H E S T R A → A R T S E O R C H

So the code takes the part after the first four letters (that is, from the 5th letter to the end), reverses that part, and then appends the first four letters unchanged.

In other words: code = reverse(original[5..end]) + original[1..4].

Apply this rule to DREAMLAND:

First four letters = DREA

Remaining part = MLAND

Reverse the remaining part: DNALM

Append the first four letters: DNALM + DREA = DNALMDREA

Thus the coded form of DREAMLAND is DNALMDREA (Option C).
