\(E°\) value of \(Ce^{+4}|Ce^{+3}\) is \(1.74\ V\), which suggests that it is a very good oxidising agent.
So, the correct option is (B): It will prefer to gain electron and act as an oxidizing agent.
The portion of the line \( 4x + 5y = 20 \) in the first quadrant is trisected by the lines \( L_1 \) and \( L_2 \) passing through the origin. The tangent of an angle between the lines \( L_1 \) and \( L_2 \) is:
