First, we must calculate the distance between the points to know the measure of the sides
We need to use the next equation
![d=\sqrt[2]{(x_2-x_1)^2+(y_2-y_1)^2}](https://img.qammunity.org/2023/formulas/mathematics/college/slh4ifnje25wmpw0d1refnrhqm5b4mqumv.png)
AC:
![AC=\sqrt[]{(-2-(-4))^2+(5-(-1))^2}=\sqrt[]{4+36}=\sqrt[]{40}](https://img.qammunity.org/2023/formulas/mathematics/college/hzpunjmk2zzw73h01306apzbpz1i85a57d.png)
AB:
![AB=\sqrt[]{(-2-3)^2+(5-(-3))^2}=\sqrt[]{25+64}=\sqrt[]{89}](https://img.qammunity.org/2023/formulas/mathematics/college/euf9gy1wawjxepi3ksnt2l6nr7v0w3emzt.png)
CB:
![CB=\sqrt[]{(-4-3)^2+(-1-(-3))^2}=\sqrt[]{49+4}=\sqrt[]{53}](https://img.qammunity.org/2023/formulas/mathematics/college/h0wtqk4r1ifi0ud8viy6560p5qnxusn6zp.png)
we can see that all sides have different measurements. So, it is a scalene triangle.
Finally, the answer is option #4.
