Simplification of ( 3.4567 )^2 - ( 3.4533 )^20.0034 = ?

Answer: Option A

$$\begin{array}{rl}& \text{According to the question}\\ & \frac{{\left(3.4567\right)}^2-{\left(3.4533\right)}^2}{0.0034}\\ & \left[\because a^2-b^2=\left(a+b\right)\left(a-b\right)\right]\\ & \Rightarrow \frac{\left(3.4567+3.4533\right)\left(3.4567-3.4533\right)}{0.0034}\\ & \Rightarrow \frac{6.91\times 0.0034}{0.0034}\\ & \Rightarrow 6.91\end{array}$$
