This symbolic design represents manufacturing prowess, industrial power, strength, national pride, and the technological progress of the nation under the campaign.\n\nWhy others are wrong:\nOption B is incorrect because an eagle is not part of the logo. Option C is incorrect as the chakra mentioned is not the symbol.

Correct answer (Option B):\nGiven data arranged in ascending order: 0, 0, 1, 1, 2, 2, x, 3, 3, 4, 5, 7\nTotal number of terms (n) = 12 (an even number)\nFormula: Median = ((n/2)th term + ((n/2) + 1)th term) / 2\nStep 1: 6th term is 2, and 7th term is x.\nStep 2: Median = (2 + x) / 2\nStep 3: 2.5 = (2 + x) / 2\nStep 4: 5 = 2 + x\nStep 5: x = 5 - 2 = 3\nAnswer: 3\nOption B is correct.\n\nWhy others are wrong:\nOption A is incorrect because if x = 2, the median would be (2+2)/2 = 2, not 2.5. Options C and D are incorrect because substituting them into the formula yields medians of 3 and 1, respectively, which do not match the given value of 2.5.\n\nStudy tip:\nWhen finding the median of an even number of observations, always calculate the average of the two central terms after sorting.

Option C is incorrect as the relationship is direct sibling, not an aunt. Option D is wrong because grandmother belongs to two generations above.\n\nStudy tip:\nIn blood relation puzzles, always decode phrases from back to front, focusing on terms like 'only son' or 'only child' to simplify relationships.
