The nuclear envelope or nuclear membrane is not continuous with the Golgi apparatus; rather it is continuous with the exterior of the endoplasmic reticulum.
Nuclear envelope is a double-layered membrane built from lipid bilayer. The nuclear membrane consists of nuclear pores, which are made up of proteins and majorly function in the passing of selected substances in and out of the nucleus. Hence, all the other statements a,c,d are correct.

<span>Tertiary</span> structure - three-dimentional structure of one polypetide chain.
Proteins are considered as for their conformation in four different stages:
Primary structure is referred solely to the sequence of amino acids<span> in the polypeptide chain.
</span>Secondary structure is the immediate basic folding of a protein and it can be α-helix and β-sheets.
Tertiary structure is the three-dimentional folding of a singles polypetide.
Quaternary structure is the thee-dimenional structure that results from the combination of two or more individual polypetides working as single protein.
