glucose d has a great tendency to be converted into cyclic

Glucose - $$D$$ has a great tendency to be converted into cyclic isomer. Which two carbon atoms get joined through $$'O'$$ to form this hemiacetal ?

A. $${C_1}\,\,{\text{and}}\,\,{C_4}$$

B. $${C_1}\,\,{\text{and}}\,\,{C_5}$$

C. $${C_1}\,\,{\text{and}}\,\,{C_6}$$

D. $${C_2}\,\,{\text{and}}\,\,{C_6}$$

Answer : $${C_1}\,\,{\text{and}}\,\,{C_5}$$

Solution :
Glucose exists as glucopyranose ( a six membered ring structure ) which is formed through $${C_1}\,\,{\text{and}}\,\,{C_5}.$$
