Explanation

Teradata supports a maximum of 2048 columns in a single table. This is a hard limit in the Teradata database architecture. Options like 256, 512, or 1024 columns are too low and don't represent Teradata's actual column capacity.

AI explanation

This is a per-table column-count limit question, and 2048 columns per table is the documented maximum for Teradata (a common context for this kind of trivia in enterprise DB question banks), which is notably higher than comparable limits in other RDBMSs (e.g., Oracle's ~1000, SQL Server's 1024, PostgreSQL's ~1600). The other options - 256, 512, 1024 - are limits associated with other systems or older versions, not the number being tested here. Without more source context this specific figure can vary by product, but 2048 matches the platform this question set appears to target.
