Answer:
D) Because it can share four electrons in covalent bond.
Explanation:
The correct option is Option D.
Because it can share four electrons in covalent bond.
All other are incorrect because,
A = it can share four electrons in ionic bond.
Carbon share its electron and form covalent bond. It can not form ionic bond.
B = Because it can share six electrons inmetallic bond.
It is also incorrect because metallic bond is only formed by the metals and also there are only 4 valance electrons in carbon not six.
Option C = Because it can share four electrons in hydrogen bonds.
It is also incorrect because carbon can not form hydrogen bonds.

The patellar reflex can be defined as the kicking movement of the lower leg which occurs with a sudden twitch when the patellar tendon of a person is tapped. This patellar tendon is present below a person's kneecap. This reflex happens only when the leg is bended. It is impossible for patellar reflex to occur if the leg is straight as the quadriceps muscles are already contracted and a sudden kicking movement of the leg in such state could not be elicited. The patellar reflex protects the quadriceps from stretching too much.
