Two words, which have a certain relation, are paired. Select a correct option to substitute the question mark so as to make a similar relational pair with the word given after double colon (::)

Prima facie : on the first view :: in pari delicto : ?

The correct answer is Both parties equally at fault.

Step-by-step Explanation:

1. Analyze the Given Pair:
The first pair gives a Latin legal phrase and its English meaning:
Prima facie means "on the first view" or "at first sight".

2. Apply the Relation to the Target Phrase:
We need to find the English translation/meaning of the Latin legal phrase in pari delicto.
The phrase in pari delicto (short for in pari delicto potior est conditio defendentis) literally translates to "in equal fault" or "both parties being equally at fault".

3. Evaluate the Options:
- Both parties equally at fault: Correct, this is the exact legal definition of in pari delicto.
- While litigation is pending: This corresponds to the phrase lis pendens.
- A remedy for all disease: This refers to a "panacea".
- Beyond powers: This corresponds to the phrase ultra vires.

Therefore, the word that replaces the question mark to complete the analogy is Both parties equally at fault.
