The value of coses260° + sec260° - cot260° + tan230° will be?

Answer: Option D

$$\begin{array}{rl}& \text{cose}{\text{c}}^{2}60^{\circ }+\text{se}{\text{c}}^{2}60^{\circ }-\text{co}{\text{t}}^{2}60^{\circ }+\text{ta}{\text{n}}^{2}30^{\circ }\\ & ={\left(\frac{2}{\sqrt{3}}\right)}^2+{\left(2\right)}^2-{\left(\frac{1}{\sqrt{3}}\right)}^2+{\left(\frac{1}{\sqrt{3}}\right)}^2\\ & =\frac{4}{3}+4-\frac{1}{3}+\frac{1}{3}\\ & =\frac{16}{3}\\ & =5\frac{1}{3}\end{array}$$
