Read the assertion and reason then select the best option::
1) Assertion: When a glass rod is rubbed with a silk cloth, the glass rod acquires a positive charge, and silk becomes negative.
Reason: The glass rod loses electrons; it has a deficiency of electrons and hence acquires positive charge. But, the silk cloth has an excess of electrons. So, it becomes negatively charged.
2) Assertion: People struck by lightning receive a severe electrical shock.
Reason: Lightning carries less voltage.
