Who is authorized to define limits of any estate/holding/field for framing record or assessment?

The correct answer is District Collector. The District Collector is the chief officer of revenue administration in a district and is specifically authorized to define the limits of any estate, holding, or field for the purpose of framing records or assessment. This is a fundamental responsibility for maintaining accurate land records and ensuring proper revenue collection. While a 'Revenue Officer' is a general term, the District Collector holds the specific authority. A 'Sub-divisional Collector' operates under the District Collector, and the 'Commissioner' holds a higher administrative role, not typically involved in direct field-level limit definition.
