A
$$y'=\left(\sqrt{x+1}+\sqrt{2*x+1}+\sqrt{3*x+1}\right)\left(\frac{1}{\sqrt{x+1}}+\frac{2}{\sqrt{2*x+1}}+\frac{3}{\sqrt{3*x+1}}\right)$$
B
$$y'=\frac{\sqrt{x+1}+\sqrt{2*x+1}+\sqrt{3*x+1}}{\frac{1}{\sqrt{x+1}}+\frac{2}{\sqrt{2*x+1}}+\frac{3}{\sqrt{3*x+1}}}$$
C
$$y'=2*\left(\sqrt{x+1}+\sqrt{2*x+1}+\sqrt{3*x+1}\right)\left(\frac{1}{\sqrt{x+1}}+\frac{2}{\sqrt{2*x+1}}+\frac{3}{\sqrt{3*x+1}}\right)$$
D
$$y'=\left(\sqrt{x+1}+\sqrt{2*x+1}+\sqrt{3*x+1}\right)^{2}\left(\frac{1}{\sqrt{x+1}}+\frac{2}{\sqrt{2*x+1}}+\frac{3}{\sqrt{3*x+1}}\right)$$
