Statement 2 is correct because the target year stated for this objective is 2033.

Explanation

Statements 1 and 3 are correct: Tarapur 1 and 2 are BWR units, and Kakrapar 3 is part of the indigenous 700 MWe PHWR series.

Explanation

Statements 1 and 2 are true. The IAEA defines fission as splitting an atomic nucleus with energy release, and states that uranium-238 is the majority isotope but cannot produce a fission chain reaction. Statement 3 is false because the same source says uranium-235 is less than 1 per cent of world uranium, not more than half.

Explanation

The Assertion is true because the Atomic Energy Establishment, Trombay was renamed Bhabha Atomic Research Centre after 1966. The Reason is also true because the cited trigger was Homi Jehangir Bhabha's death in 1966, and that directly explains why the institution received Bhabha's name. Treating the reason as unrelated misses the stated causal link, and denying either statement contradicts the cited fact.
