Solution

The correct options are
B Alcohol (A) on heating with copper gives formaldehyde
C Halide (B) undergoes SN1 reaction most readily


Since the tertiary carbocation formed which is more stable so reaction will follow SN1 mechanism.

So the tertiary butyl iodide and methnol will formed as product.

Methanol will oxidised to give formaldehyde.

Options B and C are correct.
