Select the correct indirect form of the given sentence.

I said to him, “ let us go for a ride.”

I proposed to him that we should go for a ride.

The correct indirect form of the given sentence is:

I proposed to him that we should go for a ride.

The other options are incorrect for the following reasons:

• I told him that to go for a ride. The infinitive "to go" is unnecessary in indirect speech.
• I proposed to him that we should go for a ride. The reporting verb "proposed" is more formal than the reporting verb "suggested". In this case, it is more likely that you would simply suggest going for a ride, rather than proposing it.
• I suggested that they should go for a ride. The pronoun "they" should be replaced with the pronoun "him", since the speaker is speaking to one person.
• I advised him for a ride. The reporting verb "advised" is not typically used to report suggestions.
