Dear studnet 
a mole is the quantity of a substance whose weight in grams is equal to the molecular weight of the substance. Thus 1 mole of glucose weighs 180 g.

Glucose is a simple sugar with the molecular formula C6​H12​O6​.It is soluble in water and acetic acid.
 
Molar mass of glucose can be calculated by the sum of relative atomic masses of atoms in a molecule of a substance.
 
As we know, atomic mass of C = 12
                      atomic mass of H = 1
                      atomic mass of O = 16
 
Molar mass of C6​H12​O6​ = 6×12+1×12+6×16 = 72+12+96 = 180
 
So, the molar mass of glucose is 180g. 
 
(A)  180g is correct answer.

Let us look for the atomic masses of carbon (C), hydrogen (H) and oxygen (O).

C = 12

H = 1

O = 16

∴ The molar mass of the glucose is

⇒ 12 x 6 + 1 x 12 + 16 x 6

⇒ 72 + 12 + 96

= 180
