Rokitansky-Küster-Hauser (RKHS) syndrome, also known as Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, is a disorder characterized by the absence of or underdeveloped müllerian structures in females. Here's a detailed breakdown of the question:

1. Understanding the Condition:
   • Primary Amenorrhea with Mullerian Agenesis: This condition is characterized by the absence of menstrual periods (amenorrhea) due to mullerian duct anomalies, which include the underdevelopment or absence of the uterus and the upper part of the vaginal canal.
   • Renal Abnormalities: It is common for individuals with MRKH syndrome to have associated renal abnormalities, such as horseshoe kidney or unilateral renal agenesis.
   • Normal Hormone Profile: Despite the structural anomalies, the hormonal profile in individuals with this syndrome is typically normal. This means normal functioning ovaries, which results in the development of secondary sexual characteristics like normal breast development.
2. Evaluation of the Options:
   • Since the syndrome encompasses all the mentioned conditions - primary amenorrhea due to mullerian agenesis, the presence of renal abnormalities, and a normal hormone profile - the correct answer is "All of the above."
3. Conclusion: Rokitansky-Küster-Hauser syndrome is indeed associated with primary amenorrhea with mullerian agenesis, renal abnormalities, and a normal hormonal profile. Therefore, the choice "All of the above" accurately reflects the characteristics of this syndrome.
