Choose the incorrect sentence.

The correct answer is Option A (I met Meena upon the way to my office.).

Key Points:
• The correct standard idiomatic preposition with 'the way' is 'on the way' (e.g., 'on the way to my office'), NOT 'upon the way'. Hence, sentence 1 is incorrect.
• Sentence 2: 'jumped into the river' correctly uses 'into' to denote motion directed towards the interior of water.
• Sentence 3: 'caught the thief by the arm' correctly uses 'by' for holding/catching parts of the body.
• Sentence 4: 'agree to your proposal' is correct ('agree with' a person, 'agree to' a plan/proposal).
• Key Takeaway: The correct idiom is 'on the way to', never 'upon the way to'.
