Comprehensive Explanation

The exhibit contains a JCR-SQL2 query that selects repository nodes of type nt:base where the status property equals STARTED .

To support this query efficiently through a Lucene index, the index definition must include an applicable node-type rule and a property definition capable of evaluating the equality restriction.

Option D provides the required nt:base index rule. Because the query operates against nt:base , the index must support the relevant node types rather than restricting its definition to an incompatible resource type.

Option C enables property indexing for status by setting propertyIndex=true . This tells the Lucene index to maintain property values suitable for query constraints such as equality comparisons.

Option A is incorrect because propertyIndex=false does not enable the required property-based lookup.

Option B is incorrect because aggregation is used principally to incorporate child-node content into a parent node's index representation, especially for full-text scenarios. It is not required for this direct property comparison.

An appropriately defined Lucene index can therefore support the query using the nt:base index rule and the indexed status property.

Implementation note: These are the necessary additions among the supplied choices, assuming a suitable Lucene index already exists. The complete index also needs appropriate index-definition properties, and production indexing should avoid unnecessarily broad repository scans.
