Step 1: Understanding the Concept:
The sentence expresses the Finance Minister's belief about future growth.
Step 2: Detailed Explanation:
"Confident" expresses a positive belief. "Post" as a verb means to achieve or record (a growth rate). "Assured" is usually used as "assured that" or "assured of." "Convinced, ensure" works but "ensure" implies direct control, which a minister may not have over growth. "Proposed" is past tense. "Challenged" gives negative meaning. "Confident, post" is the most appropriate.
Step 3: Final Answer:
