In a certain code language, if BIOLOGY is coded as CJPMPHZ, then how is ASTRONOMY coded in that same language?

The correct option is BTUSPOPNZ.

Step-by-step Explanation:

First, let's analyze the rule used to code BIOLOGY into CJPMPHZ:
Each letter in the original word is shifted forward by 1 position in the English alphabetical order (+1 pattern):

B + 1 = C
I + 1 = J
O + 1 = P
L + 1 = M
O + 1 = P
G + 1 = H
Y + 1 = Z

Now, applying the exact same rule (+1 shift for each letter) to the word ASTRONOMY:

A + 1 = B
S + 1 = T
T + 1 = U
R + 1 = S
O + 1 = P
N + 1 = O
O + 1 = P
M + 1 = N
Y + 1 = Z

Therefore, ASTRONOMY is coded as BTUSPOPNZ in that language.
