detailed solution
Correct option is D
Given A=1.0 m±0.2 mB=2.0 m±0.2 mx=AB=1.0×2.0=1.414 mRounding-off to two significant digits,x=AB=1.4 mNow, Δxx=12[ΔAA+ΔBB]=12[0.21.0+0.20.2]=0.62×2.0Δx=0.6×x2×2.0=0.15×1.414=0.2121Rounding-off to one significant digits, Δx=0.2 mThus, AB=1.4 m±0.2 mTalk to our academic expert!
