**Core Concept**
The question is testing the knowledge of intracellular receptors, specifically those found in the nucleus. Intracellular receptors are a type of nuclear receptor that directly interacts with the DNA in the nucleus to regulate gene expression. They are activated by various ligands, including hormones and drugs.

**Why the Correct Answer is Right**
Intracellular receptors, including nuclear receptors, are found in the cytoplasm and nucleus. They play a crucial role in regulating gene expression in response to various signals. The correct answer is likely to be a receptor type that is not typically found in the nucleus.

**Why Each Wrong Option is Incorrect**
**Option A:** Glucocorticoid receptors are a type of nuclear receptor that is found in the nucleus. They are activated by glucocorticoids, such as cortisol, and play a key role in regulating gene expression in response to stress.
**Option B:** Androgen receptors are also a type of nuclear receptor that is found in the nucleus. They are activated by androgens, such as testosterone, and play a key role in regulating gene expression in response to sex hormones.
**Option C:** Estrogen receptors are a type of nuclear receptor that is found in the nucleus. They are activated by estrogens, such as estradiol, and play a key role in regulating gene expression in response to sex hormones.

**Clinical Pearl / High-Yield Fact**
Intracellular receptors, including nuclear receptors, are an important class of receptors that regulate gene expression in response to various signals. Understanding the role of these receptors is crucial in the diagnosis and treatment of various diseases, including hormone-related disorders.

**Correct Answer:** D
