Explanation / Answer

1 D all of the above

There are various verities of bar codes and each have their own manner of reading. Alo bar code readers are variety in types.

2 True

The above option is true. Bar code has to be as short as possible so that it is not occupying lot many spaces. The maximum information has to be there in minimum space.

3 False

The above statement is false. Same start and end character is not a condition in Code 2/5 and code 2/5 interleaved

4 The spaces are part of the code

The 128 barcodes have 3 bars and 3 spaces and 11 modules. So the spaces are the part of the barcode.
