Which among the following was the first 100 percent organic state in the world?

Sikkim is the right answer. It was declared the first fully organic state in the world in 2016, after a phased policy that began with the Sikkim Organic Mission in 2003. The state banned chemical fertilisers and pesticides and brought its entire farming area under organic certification, which is why the claim was recognised internationally.

Why the others fail:

• Queensland (Australia): Australia has a strong organic sector, but no state-wide 100 percent organic declaration.
• California (USA): It has the largest organic market in the US by value, which is often confused with being first. Size of the market is not the same as converting the whole state.
• Quebec (Canada): It is a province with organic farming, but it made no such state-wide claim.

The core concept is organic certification under the National Programme for Organic Production (NPOP, 2001), administered by APEDA. For Mains, link this to soil health, input cost reduction and export certification, along with the scheme Paramparagat Krishi Vikas Yojana (2015).

Trap: Aspirants pick the most developed or largest-market region because it sounds like a first. Check whether the option was a policy-wide conversion, not just a big organic sector.
