In which year was India's first interplanetary mission to planet Mars launched successfully ?

The correct answer is (A) 2013.

• India's first interplanetary mission, formally known as the Mars Orbiter Mission (MOM) or Mangalyaan, was successfully launched on November 5, 2013, by the Indian Space Research Organisation (ISRO) using the Polar Satellite Launch Vehicle (PSLV-C25) from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
• This historic achievement made India the first Asian nation to reach Martian orbit and the very first country in the world to successfully insert a spacecraft into Martian orbit on its very first attempt, operating at a remarkably low cost compared to global space programs.
• Options (B), (C), and (D) representing the years 2012, 2016, and 2015 respectively are incorrect because the launch readiness, mission planning, and actual lift-off of the Mangalyaan spacecraft took place precisely in late 2013, with the spacecraft successfully entering Mars orbit on September 24, 2014.
