Options

A. Gorilla
B. Rhesus
C. Gibbon
D. Orangutan

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the organism that is directly related to humans in terms of evolutionary lineage.

2. **Reviewing Primate Evolution**: To answer this question, we need to look at the evolutionary tree of primates. Humans belong to a group called hominoids, which includes several other primates.

3. **Identifying the Closest Relatives**: From the evolutionary tree:
- The common ancestor of all primates is the starting point.
- From this ancestor, several lineages branched out, including lemurs and tarsiers on the side lines.
- The main line led to the anthroid ancestors, which further branched into new world monkeys and old world monkeys.

4. **Tracing the Hominoid Lineage**: Continuing from the anthroid ancestors, we find the hominoid ancestors, which eventually led to:
- Gibbons
- Orangutans
- Gorillas
- Chimpanzees
- Finally, humans

5. **Determining the Closest Relative**: Among these, chimpanzees are the closest relatives to humans, followed by gorillas. The evolutionary closeness can be ranked as follows:
- 1st: Chimpanzee
- 2nd: Gorilla
- 3rd: Orangutan
- 4th: Gibbon

6. **Analyzing the Options**: The question provided options, and while chimpanzees were not listed, gorillas were mentioned as an option. Since gorillas are the second closest relatives to humans, they are the best answer available.

7. **Conclusion**: Therefore, the answer to the question "Who is directly related to man?" is **Gorilla**, as it is the closest option provided.
