Which file format stores tabular data as plain text with one record per line and comma-separated fields — readable by almost every tool?
A.Parquet
Parquet is binary columnar — not plain text.
B.CSV
Text rows, comma fields = CSV. Correct.
C.Avro
Avro is binary + schema — not readable text.
D.ORC
ORC is binary columnar like Parquet.
Why this answer
CSV = delimited text, human-readable, universal interchange. Parquet/ORC are compressed COLUMNAR binary formats optimized for analytics; Avro is a row-based binary format for serialization/streaming.
