Step-by-step explanation:

Answer : Option B

Explanation :

Given exp. = (0.03)2+(0.21)2 +(0.065)2(0.003)2+(0.021)2+(0.0065)2−−−−−−−−−−−−−−−−−−−−−−−−−⎷

=(0.03)2+(0.21)2 +(0.065)2(0.0310)2+(0.2110)2+(0.06510)2−−−−−−−−−−−−−−−−−−−−−−−−⎷

=100[(0.03)2+(0.21)2+(0.065)2](0.03)2+(0.21)2+(0.065)2−−−−−−−−−−−−−−−−−−−−−−−−−−−⎷ = 100−−−√= 10
