Answer :
When a user is exporting contacts to share with others, the option that is not typically available is Electronic business cards. This is because electronic business cards are usually used for individual contact sharing within email clients or specific software applications, rather than in the context of exporting and sharing contacts with others outside of a particular system or program.
The other options provided – VCARD files, XML, and CSV – are commonly used formats for exporting and sharing contact information in various applications and platforms. VCARD files are widely used for exchanging contact information, XML is a versatile format that can be used for exporting data in a structured way, and CSV (Comma-Separated Values) is a simple and widely supported format for storing tabular data.
Therefore, when considering the typical methods of exporting contacts to share with others, Electronic business cards are less commonly used compared to VCARD files, XML, and CSV.
