Correct Answer: NOITAIAPPREC

Solution : Given:
TRIGONOMETRY is written as YRTEMOTRIGON, and ACCELERATION is written as NOITARACCELE.

Divide the word TRIGONOMETRY into two halves→TRIGON/OMETRY
Reverse the second part→YRTEMO
Now, the reversed part is written first followed by the first part. part→YRTEMOTRIGON
Thus, TRIGONOMETRY is coded as YRTEMOTRIGON.
Divide the word ACCELERATION into two halves→ACCELE/RATION
Reverse the second part→NOITAR
Now, the reversed part is written first followed by the first part. part→NOITARACCELE
Thus, ACCELERATION is coded as NOITARACCELE.
Similarly, follow the same pattern for APPRECIATION –
Divide the word APPRECIATION into two halves→APPREC/IATION
Reverse the second part→NOITAI
Now, the reversed part is written first followed by the first part. part→NOITAIAPPREC

So, APPRECIATION is coded as NOITAIAPPREC in the code language. Hence, the first option is correct.
