Correct answer
B
The two six-membered cyclic hemiacetal forms of $D - (+) -$ glucose are called anomers
Correct answer
C
Hydrolysis of sucrose gives dextrorotatory glucose and levorotatory fructose
Correct answer
D

Glucose

\overset{{Br}_{2} {-H}_{2} O}{\underset{[0]}{\to}}

Glycolic acid

\to \propto - Δ -

Glucose and

β - D

Glucose

\to

Hydrolysis of sucrose given dextrorotatory glucose and levorotatory fructose,

\to

Monosaccharide cannot be hydrolyzed to give polyhydroxy aldehyde and ketones.

Hence, the correct answer is options: 'B', 'C', 'D'.
