pic is not clear, blurred. I'm answering some questions which are nearly clear
15. 0oC = 273 K = 32oF .therefore, Fahrenheit scale is showing 12 instead of 32. hence. Fahrenheit scale is incorrect (option c)
14. 41oC = 106oF ((106oF − 32) × 5/9 = 41oC) Option C
in case of any doubt, please do comment sir.
