Select the correct indirect form of the given sentence. He said, “I d…

The correct answer is Option (1) → He said that he had decided not to purchase the house because it was near the railway track.

Changing a past tense statement into indirect speech:

Change	Direct	Indirect	Why
Joining word	" " (quotation marks)	that	"That" joins a reported statement. "Said" stays, as no listener is named.
Pronoun change	I	he	He is the speaker. So "I" becomes "he".
Tense change	decided	had decided	The simple past "decided" moves one step back to the past perfect "had decided". The simple past is formed with the past form of the verb (V2). The past perfect is formed with had + past participle (V3).
Full sentence	He said, "I decided not to purchase the house because it was near the railway track."	He said that he had decided not to purchase the house because it was near the railway track.

To purchase means to buy. Other tense changes after "said" are is → was, has done → had done, will → would. Example: Priya said, "I lost my umbrella." → Priya said that she had lost her umbrella.

Why the Other Options are Incorrect?

Option 2: He said that he had decides to not purchase the house because it was near the railway track. — Incorrect. "Had" is followed by the third form. "Had decides" should be "had decided".

Option 3: He said that he had decided not to purchased the house because it were near the railway track. — Incorrect. After "to" the verb stays in its base form. "To purchased" should be "to purchase".

Option 4: He told that he had decided not to purchase the house because it was near the railway track. — Incorrect. "Told" needs the person spoken to, as in "told me". Without a listener we use "said".
