Union Government in June 2014 granted Navaratna status to 1. Engineers India Ltd. 2. Coal India Ltd. 3. India Trade Promotion Organization 4. National Buildings Construction Corporation Ltd. Select the correct answer using the code given below:

The normal activity of living carbon -containing matter is found to be about 15 decay per minute for every gram of carbon. This activity arises form the small proportion of radioactive ._6C^(14) present with the ordinary ._6C^(12) isotope. When the organism is dead, its interaction with the atmosphare which maintains the above equilibrium activity, ceases and its activity begins to drop. form the known half life (=5730years) of ._6C^(14) , and the measured activity, the age of the specimen can be approximately estimated. This is the principle of ._6C^(14) dating used in archaeology. Suppose a spacimen form Mohenjodaro gives an activity of 9 decays per minute per gram of carbon. Estimate the approximate age of the Indus Vally Civilization.
