✔ C — Both together sufficient
I alone: 2(L+B)=40 → L+B=20; not enough to find L and B. II alone: L=2B; not enough. Together: L=2B and L+B=20 → 2B+B=20 → B=6.67, L=13.33. Area = L×B = definite value. ❌ A,B,D: wrong.

✔ D — Either alone sufficient
I alone: 60% = 24 → total = 24×100/60 = 40 ✓. II alone: boys=16 (40%), so total = 16+24 — but we need % of boys. Without girls count, II alone gives 40 only if we assume 40% boys — but that's circular. Actually I alone is enough (40 students). II alone without % context: 16 boys alone doesn't give total. So A is correct. ❌ B,C,D: wrong. Correct = A.

✔ C — Both together sufficient
I: "ka pa" = "happy life" — ka could be happy or life. II: "na ka" = "good life" — ka could be good or life. Common word "ka" appears in both; common English word is "life" → ka = life. ❌ A,B,D: wrong.
