The correct answer is Virus protection.

Functions of operating system are:

• Therefore, Virus Protection is not the function of OS. It is a function of Firewall and Antivirus.

The correct answer is option 4) i.e. ∞

CONCEPT:

• ​The time period of a pendulum is given by the equation:

​\(\Rightarrow T = 2\pi\sqrt{\frac {L}{g}}\)

Where L is the length of the string of pendulum and g is the acceleration due to gravity.

EXPLANATION:

• At a height of 900 km from the earth's surface gravity is absent.

Therefore, g = 0.

Substituting g = 0,

\(\Rightarrow T = 2\pi\sqrt{\frac {L}{0}} = ∞\)

Thus, the time period of the pendulum at a distance of 900 km from the Earth will be infinite.

Conclusions:

I) Penalty for costlier books will be higher → can not be concluded from the given statement as there is no mention about the costlier books.

II) Penalty for lighter books will be lesser → can not be concluded from the given statement as there is no mention about the lighter books.

Hence, neither conclusion I nor II follows.
