Let's try...

Celluar components originating from endosymbionts organisms living within organisms, are the result of the endosymbiont becoming dependent on its host. Organelles, components of cells with specialized functions, originated from bacterial endosymbionts if they have their own separate DNA.
If mitochondria, components of most eukaryotic cells, originated from bacterial endosymbionts, then it can be inferred that

A. Mitochondria have their own separate DNA.
B. Mitochondria are a kind of organelle.
C. Some bacterial endosmbionts became dependet on their cellular hosts.
D. Mitochondria are the only organelles with their won separate DNA.
E. DNA is the result of endosmbionts becoming dependent on their hosts.

I was confused between A and C. I will go with C. The reason is that although mitochondria originated from bacterial endosymbionts, it is not mentions that these are components of specialized functions. Hence, C should be correct.

separate DNA holds a condition on 'specialize functions'. It is not clear whether mitrocondia has any specialized funtion so A is wrong.
B is too specific.
C seems good
D 'only' - extreme
E New information on DNA.

1) Organelles, components of cells with specialized functions, originated from bacterial endosymbionts if they have their own separate DNA.
2) If mitochondria, components of most eukaryotic cells, originated from bacterial endosymbionts....

The way I interpreted is:

"X", componenents of cells with ...., originated from bacterial endosymbionts if they have their own separate DNA.
Mitochondria, component of .........., originated from bacterial endosymbionts. Therefore, they should have their own DNA.

Hence IMO (A), what is OA?

According to your reasoning even this is also righ to say that Mitochondria are a type of organelles!!!
But then there is no statement that certifies that bacterial endosymbionts only produce organelles. So you cant presume that. These are two different entities.
X originates from Y if Z is present
A originates from Y (if z is present then X=A)
A originates from Y (if z is not present then X!=A)

So there are both the possibilities. Z might be there or Z Z might not be there.

The approach i tried for this question is start canceling what cannot be inferred from the given argument. C is left out.

OA is posted by Richardson who posted this question.
