First 2 years of college, both the streams contain the same subjects but the last 2 years we have more of the application part in information Technology and the architecture part in computer science and engineering. Unless you wanna purse for GATE exam in future the choice should not matter. Computer science and engineering part is preferred more over IT because of the Completeness of the course.

Trypan blue is a stain used to quantify live cells by labeling dead cells exclusively. Because live cells have an intact cell membrane, trypan blue cannot penetrate the cell membrane of live cells and enter the cytoplasm. In a dead cell, trypan blue passes through the porous cell membrane and enters the cytoplasm.

Notice that the denominator is of the form of a13−b13a^{\frac{1}{3}}-b^{\frac{1}{3}}a31−b31 [a=2,b=1]
We know a3−b3=(a−b)(a2+b2+ab)a^3-b^3=(a-b)(a^2+b^2+ab)a3−b3=(a−b)(a2+b2+ab)
We can also write this as,
a−b=(a13−b13)(a23+b23+a13⋅b13)a-b=(a^{\frac{1}{3}}-b^{\frac{1}{3}})(a^{\frac{2}{3}}+b^{\frac{2}{3}}+a^{\frac{1}{3}}\cdot b^{\frac{1}{3}})a−b=(a31−b31)(a32+b32+a31⋅b31)
Observing this we multiply the numerator and denominator by (223+12+213⋅1)(2^{\frac{2}{3}}+1^2+2^{\frac{1}{3}}\cdot1)(232+12+231⋅1) and using above identity we get 1 in the denominator and 413+213+14^{\frac{1}{3}}+2^{\frac{1}{3}}+1431+231+1 in the numerator,i.e., option c).
