Which is correct?
- a)
<body color= 'yellow'> - b)
<body bgcolor= 'yellow'>(correct answer) - c)
<body background> yellow<body> - d)
<body background= 'yellow'>
Answer and explanation
Correct answer: (b) <body bgcolor='yellow'>
In legacy HTML, bgcolor is the <body> attribute that sets the page's background colour; the HTML standard tells browsers to treat it as the CSS background-color property. So <body bgcolor='yellow'> gives the page a yellow background.
Why the other options are wrong
- (a)
<body color='yellow'>:<body>has nocolorattribute (the old text-colour attribute wastext), so nothing changes. - (c)
<body background> yellow<body>: malformed:backgroundhas no value, the word yellow is just page text, and a second<body>appears instead of</body>. - (d)
<body background='yellow'>:backgroundexpects the URL of an image, which becomes the CSSbackground-image; the browser would look for an image file named "yellow", not use the colour.
Exam note: The printed paper has 'yello' in options (a) and (b); the published key is (b). Read literally, yello is not a colour name: the legacy colour parser turns every non-hex letter into 0, so it becomes #0e0000 (almost black). The intended value is clearly yellow. Also, bgcolor and background on <body> are obsolete in current HTML; today write body { background-color: yellow; } in CSS.
Tip: bgcolor = background colour; background = background image.

Which is not linear?
- a)Linked list
- b)array
- c)graph (correct answer)
- d)None
Answer and explanation
Correct answer: (c) graph
A graph is non-linear: a vertex can be joined by edges to many other vertices, so the elements do not lie in one sequence and there is no single "next" element.
Why the other options are wrong
- (a) Linked list: each node points to the next one, forming one chain; linear.
- (b) array: elements are stored one after another by index; linear.
- (d) None: wrong, because the graph is not linear.
Tip: Linear = array, linked list, stack, queue. Non-linear = tree, graph.
