Short answer

Part a)

b)

c)

Step-by-step solution

Introduction (Part a)

• Carbohydrates are the most abundant class of organic molecules on the planet.
• Carbohydrates account for approximately $75\%$of the dry planet's bulk.

Explanation(Part a)

• Fischer devised a simplified method for depicting the atom configurations around the chiral carbons.
• Vertical lines in this three-dimensional structure represent bonds that extend backward from a carbon atom, while horizontal lines represent bonds that extend forward.
• The intersections of horizontal and vertical lines depict chiral carbon atoms.

Draw the Fischer projection for given structures(Part a)

In this structure, Hydroxy and Bromide have wedged bonds, which means that in the Fischer projection there are horizontal.

Explanation(Part b)

• Vertical lines in this three-dimensional structure represent bonds that extend backward from a carbon atom, while horizontal lines represent bonds that extend forward.
• The intersections of horizontal and vertical lines depict chiral carbon atoms.

Draw the Fischer projection for given structures(Part b) 

In this structure Chloride and Bromide have wedged bonds, which means that in the Fischer projection there are horizontal.

Explanation(Part c)

• Vertical lines in this three-dimensional structure represent bonds that extend backward from a carbon atom, while horizontal lines represent bonds that extend forward.
• The intersections of horizontal and vertical lines depict chiral carbon atoms.

Draw the Fischer projection for given structures(Part c) 

In this structure hydroxy and hydrogen have wedged bonds, which means that in the Fischer projection there are horizontal.
