Step 1: Recall the post 2000 shift.
Since 2000 Indian workers have been moving out of farming into industry and services.
Step 2: Check option A.
This move from low productivity farming to higher productivity non farm work is exactly the structural change seen after 2000. So A is correct.
Step 3: Check option B.
Construction has soaked up many rural and semi skilled workers, so it has high employment elasticity. So B is correct.
Step 4: Check option C.
With more machines and automation, production has become less labour heavy, not more. So C is wrong.
Step 5: Check option D.
Services like IT and finance have led India's growth, so D is correct.
\[ \boxed{(A),\ (B)\text{ and }(D)} \]
