Select the correct statement among the following:

$CHO-(CHOH)_4-CH_2OH \xrightarrow{Br_2/H_2O} P$; $P$ is:

Which of the following are non-reducing sugars?
$I$. Glucose
$II$. Fructose
$III$. Maltose
$IV$. Sucrose
$V$. Galactose

Consider the following molecules:
Glucose $(K)$,Mannose $(L)$,Galactose $(M)$,$\alpha-Glucose$ $(N)$,$\beta-Glucose$ $(O)$
The correct set of epimer and anomer is respectively:
Epimer - Anomer

What are $\beta - D - \text{glucose}$ and $\beta - D - \text{galactose}$ known as in relation to each other?

Given below are two statements:
Statement $I$: Sucrose is dextrorotatory. However, sucrose upon hydrolysis gives a solution having a mixture of products. This solution shows laevorotation.
Statement $II$: Hydrolysis of sucrose gives glucose and fructose. Since the laevorotation of glucose is more than the dextrorotation of fructose, the resulting solution becomes laevorotatory.
In the light of the above statements, choose the correct answer from the options given below.
