Explanation:

Answer 2

The answer is c. putting.

• Here, 'putting' acts as a gerund. It is a verb which is acting as a noun. As long as a helping verb is not placed before 'putting,' it cannot become continuous tense.

• Another alternative could be 'to put.' However, that option is not present.  

• 'To putting' is in the incorrect format. 'To' always takes the simplest form of the verb. 'Putting' cannot be preceded by to.
