CCK
KOS
NRV
RVZ
Answer is Right!
Answer is Wrong!
The correct answer is C. NRV.
The pattern is to take the first two letters of the previous term and add the next letter of the alphabet. So, DHL becomes PTX, PTX becomes BFJ, and BFJ becomes NRV.
A. CCK is not a valid continuation of the pattern because it does not follow the rule of adding the next letter of the alphabet.
B. KOS is not a valid continuation of the pattern because it does not follow the rule of adding the next letter of the alphabet.
D. RVZ is not a valid continuation of the pattern because it does not follow the rule of adding the next letter of the alphabet.
