The aim of the Rural Electrification Policy, which was notified by the Government of India in August 2006, was to ensure access to electricity for all households. India planned to achieve this objective by the year 2009, as indicated in the correct answer, option 2.

Option 1, 2008, is incorrect as the target year was after the implementation of the policy not two years into it. Option 3, 2010, and Option 4, 2012, are also incorrect as these years were beyond the specified target year. This explains why the correct answer is 2009 which aligns with the goals set by the Indian government under this policy.
