○ 5

Explanation:

Step1: Recall distance formula

The distance $d$ between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step2: Substitute given points

Let $(x_1,y_1)=(1,2)$ and $(x_2,y_2)=(4,6)$. Substitute into formula:
$d=\sqrt{(4-1)^2+(6-2)^2}$

Step3: Calculate differences

Compute the squared differences:
$d=\sqrt{(3)^2+(4)^2}=\sqrt{9+16}$

Step4: Simplify the expression

Add and take the square root:
$d=\sqrt{25}=5$
