Solution

The correct answer is option 3.

Key Points

• XML was created with the aim of transporting data, with an emphasis on what data is.
• HTML was developed with the intention of presenting data with an emphasis on how it appears.

Statement A: ​FALSE:

HTML is a collection of tags that tell web browsers how to view text and images on a website.

Statement B: TRUE 

While XML specifies a syntax for representing data, the meaning of data varies by application.

Statement C: TRUE  

XML is case sensitive and hence < Letter >, < LETTER > and < letter > are three different tags in XML.

∴ Hence the correct answer is (B) and (C) only.
