Answer: D.  Nice one crossrulz, DavidCorney, SOM19, LordNobady, MrStevenUND & gnshmrthy.

Flatten to String is converting each successive byte of the data in into a character.  The number of bytes in each of the different numeric types is built into the array.

Can I get a little more explaination on this.

Hi sahils.  Flatten to String will flatten anything to a binary string.  The data you pass to flatten is translated on a byte by byte basis into binary.  NOTE:  If the data type you pass to Flatten to String is a non-scalar type (of undefined size) such as a strings and arrays  Flatten to String will by default add header information to the beginning of the string that defines the size of the non-scaler type that was translated.

It is used a lot in TCP/IP communications since you have to write a string out.  I have also had to use it when talking to a PLC over Ethernet/IP.

One of the more unexpected places I use it is for interprocess communications.  I like to use queues with a string data type and then I can embedd the command and any parameter data in the string.  It is a derivative of using a cluster with a string and variant for sending commands.

As far as knowing what the data in the binary string is, well, you don't know.  You just have to know who sent the data and how they want you to interpret it.
