C Correct answer
Explanation

Let CP = 1 per article. For 15 paid + 1 free = 16 articles, total CP = 16. After 4% discount, SP = 0.96 MP per article. Total SP = 15 × 0.96 MP = 14.4 MP. With 35% profit, SP = 1.35 × 16 = 21.6. Solving: 14.4 MP = 21.6, so MP = 1.5, meaning marked price is 50% above cost price.
