Answer: The correct option is
(B) √10
Step-by-step explanation: We are given to find the distance between the points (1, 2) and (4, 3).
We have the following distance formula :
DISTANCE FORMULA : The distance between the points (a, b) and (c, d) is given by
![D=√((c-a)^2+(d-b)^2).](https://img.qammunity.org/2019/formulas/mathematics/high-school/eoych8mexq5ymu3drwfi7zdgrkw1oi30nw.png)
Therefore, the distance between the points (1, 2) and (4, 3) is given by
![D\\\\=\sqt{(4-1)^2+(3-2)^2}\\\\=√(3^2+1^2)\\\\=√(9+1)\\\\=√(10).](https://img.qammunity.org/2019/formulas/mathematics/high-school/92ete79kvisxy10rv4wvennfwm7gyivtod.png)
Thus, the required distance between the given points is √10 units.
Option (B) is CORRECT.
