Statement (i) is correct: The report did show an increase in the tiger population from 1706 in 2010 to 2226 in 2014, which is approximately a 30% increase. Statement (ii) is incorrect: While Karnataka and Tamil Nadu showed significant increases, Kerala's tiger population actually decreased from 152 in 2010 to 136 in 2014 according to the report. Thus, stating "largest increase was recorded in Kerala..." makes the statement false. Statement (iii) is likely intended to be incorrect: While the Mudumalai-Bandipur-Nagarhole-Wayanad Complex (MBCW), part of the Western Ghats landscape, is indeed a critical tiger area with a very high population (estimated over 570 in the broader landscape/complex in 2014, and often cited as the world's largest contiguous population), the exact figure, the specific boundaries of the "Complex" as defined in the report, and the definitive assertion of it being the world's largest in a single complex could be the points of intended inaccuracy or specific definition used in the report which might make the statement not entirely correct as phrased. Given that (ii) is definitively incorrect, and option B includes (ii) and (iii), it is probable that (iii) is also deemed incorrect by the question setter.
