false

Either A or B

|
None of the above
|
Explanation:
Detailed explanation-1: -A rough surface will have more friction because on the rough surface there will be more irregularities. They will cause interlocking which in turn creates more frictional force. For a smooth surface, irregularities and interlocking is less and hence has very less friction.
Detailed explanation-2: -A smooth surface produces less friction than a rough surface.
Detailed explanation-3: -Smooth surfaces produce the least friction.
Detailed explanation-4: -False. Explanation: Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them.
