Which of the following glucose transporters is insulin-dependent?

Given below are two statements:
Statement $I$: $A$ protein is imagined as a line, the left end represented by the first amino acid ($N$-terminal) and the right end represented by the last amino acid ($C$-terminal).
Statement $II$: Adult human haemoglobin consists of $4$ subunits (two subunits of $\alpha$ type and two subunits of $\beta$ type).
In the light of the above statements, choose the correct answer from the options given below:

Select the correct option for the following matches:

$(1)$ Carbohydrate	$(a)$ Ester bond
$(2)$ Lipid	$(b)$ Glycosidic bond
$(3)$ Protein	$(c)$ Phosphodiester bond
$(4)$ Nucleic acid	$(d)$ Peptide bond

Assertion $(S)$: The measure of disorder in a biological system is called free energy.
Reason $(R)$: The energy available in a biological system to perform work is called entropy.
$(A)$ Both $S$ and $R$ are true,and $R$ is the correct explanation of $S$.
$(B)$ Both $S$ and $R$ are true,but $R$ is not the correct explanation of $S$.
$(C)$ $S$ is true and $R$ is false.
$(D)$ $S$ is false and $R$ is true.
$(E)$ Both $S$ and $R$ are false.
