Hint: It is a middle serous covering of a part of sex organ in males and it is one of the three coverings present in them. First of all you should know what tunica vaginalis is to solve this question. It is the serous covering of the testes which pouch a serous membrane. Testes is the sex organs in males and it produces sperms and male sex hormones and it is covered by fibrous covering which are:
-Tunica albuginea which is the outer covering.
-Tunica vaginalis which is the middle covering.
-Tunica vasculosa which is the inner covering.

Complete answer:
If we look at the options, then option A is Ovaries of female, this is the incorrect option as tunica vaginalis is the middle covering of the testes and testes is the male sex organ, therefore this option is incorrect one and it gets eliminated.
Moving to option B which is Testes of male. It is the right option since it is one of the coverings of the fibrous membrane of testes and it is the middle covering of testes which is a pouch like serous membrane. Therefore, this is the correct option.
Moving to option C which is Vagina of female, you might get confuse with this option since in the name of tunica vaginalis, vagina related name is there but no it is the incorrect option since it is not a part of female but it is a part of sex organ of males which is the middle serous membrane covering the testes. Therefore, this option is incorrect and it gets eliminated.
Last option is D which is none of the above, this is incorrect as the correct option is there in the other options.

Thus, the correct answer is option B which is the testes of male.

Note: There are membranes which cover the testes and there is presence of three serous membranes covering the testes and tunica vaginalis is one of them It is the middle membrane of the outer covering of testes and thus it makes option C the correct one.
