The Correct Option is 4×10¹ (4)TH option.
As this is represented in Scientific Notation... It Clearly Displays that This measurement has only 1 Significant digits No matter in Whuch ever derived unit The measurement is represented... Like in Km =4×10¹ ×10^(-3)=4×10^(-2)Km Or mm =4×10²mm
As for(1) 40m ... Here 1 Significant Figures... But when this is represented in Km=0.04Km gives 2 Significant Figures...
