Explanation / Answer

Hi,

Option 2

The correct answer is option number 2 in your list of options.

Explanation- In the search string we have an opening tag'<' which means the string must begin with < character. After that we have '[a-z]+' which means 1 or more occurance of any small case alphabets from a to z. After that we have one space in the string, Post that we have '[a-z]+="' which means 1 or more occurance of small case alphabet followed by an equal to sign and a double quote sign. Post that we have '[a-z]*' which means 0 or more occurance of small case a to z letter. So it is not necessary that we need to have lettrs after double quotes. Finally, string should end with closing html tag >.
