The correct answer is C. 1 and 2.
Saturated hydrocarbons are hydrocarbons that have all of their carbon atoms bonded to the maximum number of hydrogen atoms possible. They are also known as alkanes. Saturated hydrocarbons can undergo substitution reactions, which are reactions in which one or more atoms in a molecule are replaced by other atoms. For example, methane (CH4) can undergo substitution reactions to form ethane (C2H6), propane (C3H8), and butane (C4H10).
Carbon black is a form of elemental carbon that is produced by the incomplete combustion of hydrocarbons. It is a black, powdery solid that is used in a variety of applications, including tires, inks, and paints. Carbon black is obtained when methane is heated in the absence of air.
Therefore, both statements 1 and 2 are correct.
