Which of the following represents the anomer of the compound shown?

Four carbohydrates: glucose,lactose,sucrose,and starch are present. Different tests are carried out with these $4$ carbohydrates separately. The following observations are made:
$(a)$ Heated: It is charred.
$(b)$ $I_2$ solution: No violet colour.
$(c)$ Fehling solution: Reddish brown precipitate is observed.
$(d)$ It does not reduce copper$(II)$ acetate to $Cu_2O$. No red precipitate is observed in $5 \ min$.
Which carbohydrate satisfies all the above observations?

The artificial sweetener sucralose is $ . . . . .$.

The statement that is $NOT$ correct is

On heating with conc. $H_2SO_4$,sucrose gives

$\alpha -D(+)$ Glucose and $\beta -D(+)$ Glucose are
