You are using a tag library with prefix "generator", which supports a tag named "random". This tag generates a random number and sets it to a variable named "value". Which of the following will output this value in the page?


Select 1 correct option.
a <generator:random>value</generator:random>


b <generator:random><%=value%></generator:random>


c <generator:random><% int value;%> <%=value%></generator:random>
It'll give an exception saying value is not initialized!

d <generator:random><%getParameter("value")%></generator:random>


e None of the above.

There is no default body-content for simple/classic tags.
But if JSP were to be specified as body-content then the expression
<%=value%> would work.

You need to read up on "Variable Synchronization" topic from JSP specs to understand how the output of the custom tag works.
