Solution

XML is used to store and transport data, not to display data like HTML.

So, statement A is false.

XML defines syntax for representing data, but meaning depends on application.

So, statement B is true.

XML tags are case-sensitive.

So, <Letter>, <LETTER>, and <letter> are different tags.

So, statement C is true.

Solution

A firewall can filter packets using information present in the packet header.

It can filter packets on the basis of Source IP Address.

So, statement (A) is true.

It can filter packets on the basis of Destination IP Address.

So, statement (B) is true.

It can filter packets on the basis of TCP Source Port.

So, statement (C) is true.

It can filter packets on the basis of UDP Source Port.

So, statement (D) is true.

It can also filter packets on the basis of TCP Destination Port.

So, statement (E) is true.

Therefore, all statements (A), (B), (C), (D) and (E) are correct.

Solution

Statement $P$ is true.

JavaScript is dynamically typed. In JavaScript, variables can store values of different types at different times.

So, types are associated with values, not fixed permanently with variables.

Statement $Q$ is false.

Images can also be shown on a web page using CSS background images, SVG, canvas, object tag, embed tag, etc.

So, it is possible to show images without using the <img> tag.

Therefore, only $P$ is true.

Solution

Statement $P$ is true.

An XML document with correct syntax is called a well-formed XML document.

Statement $Q$ is also true.

If an XML document is validated against a DTD, then it is well formed and valid.

Statement $R$ is false.

An XML declaration must follow the proper XML declaration format. Without the required question-mark based syntax, it is not syntactically correct.

Therefore, only $P$ and $Q$ are true.

HTML → defines structure of web pages → (II)

DHTML → dynamic interactive web pages → (I)

XML → data storage and transport → (IV)

JAVA → object-oriented programming language → (III)

Thus matching:

(A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Solution

Frame attribute is used to specify the side of the table frame that displays border.

So, (a) $\rightarrow$ (iv)

<tr> tag is used to enclose each row in a table.

So, (b) $\rightarrow$ (iii)

Valign attribute is used for vertical alignment of content in a cell.

So, (c) $\rightarrow$ (ii)

<a> tag is used to create links in HTML.

So, (d) $\rightarrow$ (i)

Hence, correct matching is:

$(a)-(iv),\ (b)-(iii),\ (c)-(ii),\ (d)-(i)$
