Identify the correct sentence in the following examples:
(1) I have no competition for you with this prize.
(2) I have no competition with you for this prize.
(3) He hasn't got some money.
(4) I have no authority over you.

The correct answer is Option A (I have no competition for you with this prize.). [Note: This question was officially cancelled (#) by MPSC in the final key, but this option is selectable for online practice].

Key Points:
• In the official MPSC Group C Mains P1 Final Answer Key, Question 81 is explicitly marked with '#' (Cancelled/Deleted).
• Both Option 2 ('I have no competition with you for this prize' - correct use of 'competition with someone for something') and Option 4 ('I have no authority over you' - correct idiomatic use of 'authority over someone') are grammatically standard and valid English sentences.
• Because the question asked to identify 'the correct sentence' among mutually non-exclusive choices and two distinct options (Option 2 and Option 4) were both correct, MPSC cancelled the question.
• Key Takeaway: Question 81 was cancelled by MPSC because both Option 2 and Option 4 are grammatically correct sentences.
