Increase in absolute and per capita real GNP do not connote a higher level of economic development, if:

The correct answer is C. Rising real GNP per capita shows that average output has gone up, but it says nothing about who receives that output. If poverty and unemployment rise alongside, growth is not reaching people as welfare, so it cannot be read as development.

Why the others fail:

• A and B concern sectoral balance. A lopsided industry-agriculture pattern is a structural concern, but it does not by itself cancel out a rise in per capita income.
• D is a balance of payments issue. Imports outpacing exports widens the trade deficit and raises external vulnerability, but it is a macro stability concern, not a direct test of whether living standards have improved.

The core concept is the gap between growth and development. Dudley Seers argued in 1969 that the real questions are what happens to poverty, unemployment and inequality, and that GNP alone cannot answer them. Amartya Sen's capability approach extends this. For Mains, this links to inclusive growth and jobless growth debates.

Trap: Students pick D because trade deficits sound alarming. Stay with the question's wording. It asks what fails to signal development, and only the welfare indicator in C answers that directly.
