**Core Concept**
The question pertains to the embryological development of the female reproductive system, specifically the formation of the Müllerian ducts and their derivatives. The Müllerian ducts give rise to the fallopian tubes, uterus, cervix, and upper part of the vagina in females.

**Why the Correct Answer is Right**
In the presence of an absent uterus and vagina, the development of breasts and ovaries is expected to proceed normally, as these structures are formed from different embryological precursors (the mammary glands and the gonads, respectively). The Müllerian inhibiting substance (MIS), produced by the Sertoli cells of the testes in males, inhibits the development of the Müllerian ducts. In females, the absence of testes and, therefore, MIS, allows the Müllerian ducts to develop into the female reproductive tract. However, in the case of an absent uterus and vagina, it indicates a developmental issue specific to the Müllerian ducts, not the ovaries or breasts.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as the development of the ovaries and breasts would be normal in the absence of a uterus and vagina, as these structures are not derived from the Müllerian ducts.
**Option B:** This option is incorrect as the presence of a normal uterus and vagina would imply a developmental issue with the ovaries or breasts.
**Option C:** This option is incorrect as the development of the fallopian tubes, cervix, and upper part of the vagina would be affected in the case of an absent uterus and vagina.
**Option D:** This option is incorrect as it does not accurately reflect the embryological development of the female reproductive system.

**Clinical Pearl / High-Yield Fact**
In cases of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a condition characterized by an absent uterus and vagina, the ovaries and breasts typically develop normally, and these individuals are generally fertile due to the presence of functional ovaries.

**Correct Answer: A. Normal development of ovaries and breasts.**
