Let’s suppose that a few days ago your friend recommended a certain book to you, so later on you took went out and bought that book for yourself.
How would you normally relate the foregoing sequence of events in modern English?
Let’s further assume also that your friend has continued to recommend that you should buy this particular book on more than one occasion since that time, and the book is now in your possession.
This article explains that modern speaker can use either of (a) the past tense alone ("simple past") or else (b) the present tense along with a past participle ("present perfect").
As a foreigner, I am thinking of the following four options:
I bought the book that you recommended to me.
(Recent actions, just facts, no reference to the present.)
I've bought the book that you recommended to me.
(Reference to the present: I now have the book.)
I bought the book that you have recommended to me.
(Reference to the fact that the friend made the same book recommendation more than once.)
I bought the book that you had recommended to me.
(Recent action via normal past tense without a participle + earlier action via past tense with a past particple ["past perfect"].)
For me it seems that every one of those four options may have some grammatical logic justifying its use, so I cannot decide which to choose. So my question is about native speakers' habits in this scenario. How would you say it normally, whether in speaking or writing.
