Correct option is C
Given:
A: PALE
B: STAR
C: ZERO
D: CARE
Logic:
The pattern here is that three of the words can be rearranged to form other meaningful words, but one of them cannot.
PALE can be rearranged to form "LEAP."
STAR can be rearranged to form "ARTS."
CARE can be rearranged to form "RACE."
ZERO, however, cannot be rearranged to form any other meaningful word.
Final Answer: (C) ZERO
Final Correct Option: (C)
