In a certain code, ALPHABET is written as TEBAHPLA. How is DECIPHER written in that code?

The correct option is REHPICED.

To solve this coding-decoding problem, let us analyze the relationship between the original word and its coded form:
Original Word: ALPHABET
Coded Word: TEBAHPLA

Let us write down the positions of the letters in ALPHABET from left to right:
1. A
2. L
3. P
4. H
5. A
6. B
7. E
8. T

Now, let us examine the coded word TEBAHPLA:
1. T (originally the 8th letter)
2. E (originally the 7th letter)
3. B (originally the 6th letter)
4. A (originally the 5th letter)
5. H (originally the 4th letter)
6. P (originally the 3rd letter)
7. L (originally the 2nd letter)
8. A (originally the 1st letter)

This shows that the coding pattern is simply writing the original word in reverse order (from the last letter to the first letter).

Applying the same reversing pattern to the word DECIPHER:
Original Word: DECIPHER
Letters from right to left:
8th letter: R → becomes 1st
7th letter: E → becomes 2nd
6th letter: H → becomes 3rd
5th letter: P → becomes 4th
4th letter: I → becomes 5th
3rd letter: C → becomes 6th
2nd letter: E → becomes 7th
1st letter: D → becomes 8th

Combining these letters in reverse order gives REHPICED.
