**Core Concept**
The question pertains to the maximum radiation dose that can be tolerated by different tissues in the human body, which is a critical concept in **radiation oncology** and **radiation protection**. This involves understanding the effects of **ionizing radiation** on various tissues and organs. The tolerance of tissues to radiation is a key principle in minimizing damage while treating diseases like cancer.

**Why the Correct Answer is Right**
The correct answer is related to the **bone marrow**, which is known for its high sensitivity to radiation due to its high cell division rate. However, the most resistant tissues are often those with low cell division rates, such as **bone** and **cartilage**. Among the options provided, without specific details, the general principle is that tissues with lower cell turnover rates tend to be more resistant to radiation damage.

**Why Each Wrong Option is Incorrect**
**Option A:** Without specifics, it's hard to directly address each choice, but generally, options that suggest highly sensitive tissues like the **lens of the eye** or **gonads** would be incorrect because these are known to have lower radiation tolerance.
**Option B:** Similarly, if this option suggests a tissue with high cell division rates, it would be incorrect for the same reasons as above.
**Option D:** This option, if representing a sensitive tissue, would also be incorrect based on the principle that rapidly dividing cells are more susceptible to radiation damage.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that the **law of Bergonié and Tribondeau** (1906) states that radiosensitivity is directly proportional to the reproductive activity of the cells and inversely proportional to their degree of differentiation. This principle guides the understanding of tissue tolerance to radiation.

**Correct Answer:** Correct Answer: C. Bone.
