If in a certain code, 'POT' is written as ATOP and 'TRAP' is written as APART, then how is 'ARENA' written in that code?

Correct Option: (d) AANERA

Let us analyze the coding pattern from the given examples: For 'POT' written as 'ATOP': First, the letters of the word 'POT' are reversed, which gives 'TOP'. Then, the letter 'A' is added as a prefix (at the beginning) of this reversed string, resulting in A + TOP = ATOP. For 'TRAP' written as 'APART': First, the letters of the word 'TRAP' are reversed, which gives 'PART'. Then, the letter 'A' is prefixed at the beginning of the reversed string, resulting in A + PART = APART. Following this established pattern for the word 'ARENA': First, we reverse the letters of the word 'ARENA', which gives 'ANERA'. Second, we add the letter 'A' at the prefix/beginning of this reversed word, resulting in A + ANERA = AANERA. This matches option (d) uniquely. The other options are incorrect because they do not follow this dual rule of reversal and prefixing.
