The monomers that react together to form polyurethane polymer are diisocyanate and diol.
<h3>What are polymers?</h3>- Polymers are a class of natural or synthetic substances
- It is made up of small units called monomers arranged in a repeated pattern to form large molecules called macromolecules
- Cellulose and resins are examples of natural polymers
- Polyethylene and polychloroprene are examples of synthetic polymers.
Polyurethane polymer is made up of monomers diisocyanate and diol. It is mostly used in home furnishing in flexible form. The structures of monomers are as follows:

Methane was unusually high is the correct option. Hence, option B is correct.
<h3>What is methane?</h3>Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent greenhouse gases. Its chemical formula is .
As the ice compacts over some time, tiny bubbles of the atmosphere or surroundings including greenhouse gases like carbon dioxide and methane—press inside the ice. These air pocket “fossils” give samples of what the atmosphere was kind when that layer of ice formed.
Based upon past studies and insights from current GHG levels, we assume that atmospheric levels of carbon dioxide and methane were unusually low.
