Answer:
b. Disulfide bond
Explanation:
Covalent linkage or bonding is a type of bond in which electrons are shared between atoms in a compound or molecule. Each atom contributes to the shared electron.
This is the case of disulfide bonding i.e. S-S, in which two thiol groups (-SH) share electrons with one another. The process of oxidation between two cysteine (amino acid) molecules forms this bond. Hence, Disulfide bond is characterized by a covalent linkage.
Alkenes are organic compounds which contains double bonds between two carbon atoms. The formula C2H4 can be classified as an alkene since it most likely contains a double bond between the carbon-carbon atoms. An alkene has the general formula of CnH2n.
