Assertion (A): Carbon has a strong tendency to either loss or gain electrons to attain noble gas configuration. Reason (R): Carbon has 4 electrons in its outermost shell and has the tendency to share electrons with carbon or other elements.
Carbon does not have a strong tendency to lose or gain electrons completely. Instead, it has 4 valence electrons and typically shares electrons with other atoms to achieve a stable configuration. The correct answer is D: A is false but R is true.

ANSWER: [D]
Explanation: A is false but R is true.
Step 1 – Carbon’s behavior:
Carbon has 4 valence electrons. To achieve noble gas configuration, it does not strongly lose or gain electrons because gaining 4 electrons or losing 4 electrons is difficult. Instead, it shares electrons to form covalent bonds.
Step 2 – Reason (R):
R is correct: Carbon has 4 valence electrons and tends to share electrons, forming covalent bonds with itself or other elements.
Step 3 – Relation:
A is false (because carbon prefers sharing, not losing/gaining electrons).
R is true (carbon shares electrons).
