The correct option is A 33% for plains and 67% for hills
In India, 6,77,088 square kilometer or 20.6 percent of land is under forest cover (state of forest report, 2005). The amount was 30 percent at the beginning of twentieth century. The present forest cover of 20.4 percent is quite small as compared to optimum of 33 percent according to the 'National Forest Policy', 1988. It recommends 67 percent forest cover in the hills. Presently, dense forests occur in only 11.78 percent. Very dense forests occupy only 1.66 percent.
