Acknowledgments, sequencing, and flow control are characteristics of which OSI layer?
Answer: Option
Explanation:
A reliable Transport layer connection uses acknowledgments to make sure all data is transmitted and received reliably. A reliable connection is defined by a virtual circuit that uses acknowledgments, sequencing, and flow control, which are characteristics of the Transport layer (layer 4).

Even these responsibilities are carried by data-link layer (layer 2).

These functions are performed at data link layer. So why the answer is layer 4? please explain.

I think, this is the responsibility of data link layer.
Transport layer not always acknowledges the data (e.g. in UDP protocol).

These functions are performed by the datalink layer.

This answer is wrong because all these operations are performed by Data Link layer.
If it is correct then explain how it is right.

Flow control maintained by data link layer.

TCP (Transmission Control Protocol):
-> Ensure data arrives at the receiver end,
-> Ensure the data is in order,
-> Control speed at which data is sent (congestion control algorithm).
So, TCP Done Acknowledgments, sequencing, and flow control.
And TCP is present at the Transport Layer. Not at the DLL (Data Link Layer).
Therefore, The Answer is correct.
