Last month Arun went to a hill station. He spent a week there. He did not feel happy about the visit. On the way there he saw trucks laden with tree trunks coming downhill down hill. Roadsides and parks were littered. Accomodation on offer was either too expensive or not good enough. Arun decided to write a letter about the problems he faced.
Appropriate subject of the letter will be :

Options

A. Deforestation in the hills
B. Affordability of accommodation
C. Irresponsible tourists
D. Deteriorating condition of hills stations.
