A long straight wire having uniform resistance per unit length `lamda` (ohms/metre) is bent into `V`-shape as shown (angle `DAC=alpha`). A uniform and constant magnetic field `B` (tesla) exists in space which is perpendicular to the plane of `V`- shaped wired. Another straight wire `EF` of same uniform resistance per unit length `lamda` (ohms/metre) is pulled with constant velocity `u` (m/s) such that the wire `EF` is always perpendicular to side `AD` of `V` -shape (the wire `EF` is always in conducitng contact with the `V`- shaped wire at two points).At `t=0` (`t` is the time is seconds) the value of `x=0` (`x=` distance of wire `EF` from end `A` in metres)
Select the correct statements(s):

Options

A. The emf generaged in the triangular loop at any time `t` is `B u^(2)t tan alpha`
B. The emf generated in the triangular loop at any time `t` is `B u t tan alpha`
C. The induced current in the loop remains constant
D. The induced current in the loop increases with time
