The correct answer is C. TJLDMF.
The letters in the first word are rearranged to form the letters in the second word, with the first letter of the second word being the last letter of the first word, and the second letter of the second word being the first letter of the first word, and so on.
For example, in the first pair, "FIELD" and "GJFME", the first letter of "GJFME" is "G", which is the last letter of "FIELD". The second letter of "GJFME" is "J", which is the first letter of "FIELD". The third letter of "GJFME" is "F", which is the second letter of "FIELD". And so on.
In the second pair, "Sickle" and "TJLDMF", the first letter of "TJLDMF" is "T", which is the last letter of "Sickle". The second letter of "TJLDMF" is "J", which is the first letter of "Sickle". The third letter of "TJLDMF" is "L", which is the second letter of "Sickle". And so on.
The other options are incorrect because they do not follow the same pattern. For example, in option A, "RHBJKD", the first letter of "RHBJKD" is "R", which is not the last letter of "FIELD". The second letter of "RHBJKD" is "H", which is not the first letter of "FIELD". The third letter of "RHBJKD" is "B", which is not the second letter of "FIELD". And so on.
