The relationship between the words “BIOLOGY” and “ZJPMPHC” involves shifting each letter by a certain number.
If we observe the pattern, each letter in “BIOLOGY” is replaced by a corresponding letter in “ZJPMPHC” using a backward shift in the alphabet.
Similarly, we apply the same shifting pattern to the word “CHEMISTRY”, which results in the code “ZIFNJTUSD”.
The correct answer is (a) ZIFNJTUSD.
