A block of base `10 cm xx 10 cm` and height `15 cm` is kept on an inclined plane. The corfficient of friction between them is `sqrt(3)`. The inclination `theta` of this inclined plane from the horizontal plane is gradually increased frm `0^@`. Then

Options

A. at `theta=30^@`, the block will start sliding down the plane, the block will remain at rest on the plane upto certain `theta` and then it will topple
B. The block will remain at rest on the plane upto certain angle `theta` and then it will topple
C. at `theta=60^@`, the block will start sliding down the plane and continue to do so at higher angles
D. at `theta=60^@`, the block will start sliding down the plane and further increasing `theta`, it will topple a
