non current assets held for sale

Hi Sir,
I came across the question below and chose option A but I got it wrong and the explanation I am getting is”Fair value ($33m) less costs to sell ($1.5m).” I am unable to understand. Please help. Thank you.

At 31 March 20X5, Rushworth had a property with a carrying amount in the financial statements of $20m and a remaining useful life of 40 years. On 1 September it was decided that the property should be sold and it was placed with a property agent. Selling costs were estimated at $1.5m. The property is being marketed at a price of $35m although the directors have been advised that they should accept offers around $33m. At 31 March 20X6, the property remained unsold although a number of buyers had expressed an interest.

At what amount should the property be reported in the statement of financial position at 31 March 20X6?

$19.75m
$20m
$31.5m
$33.5m
