B,D Correct answer
Explanation

Merge and Lookup stages support reject links in Datastage. Merge rejects records that don't match on key columns. Lookup rejects records when lookup fails (if configured). Join and Funnel stages don't have reject links - Join handles non-matching data differently (left/right/full joins), and Funnel just combines data streams.
