Correct option is A
Given:
'FEAR' is coded as 'JJEW'

· F → J (Shift of +4)
· E → J (Shift of +5)
· A → E (Shift of +4)
· R → W (Shift of +5)
It appears that the letters alternate between a shift of +4 and +5.
let's apply it to each letter in "FLAT":
· F → J (Shift of +4)
· L → Q (Shift of +5)
· A → E (Shift of +4)
· T → Y (Shift of +5)
Thus, the code for "FLAT" is JQEY.
Correct answer is (a) JQEY.
