**Species is less general in character as compared to genus.**

**Explanation:**

To understand which of the given options is less general in character compared to genus, it is important to have a clear understanding of the hierarchy of classification in biology.

In biology, organisms are classified into a hierarchical system called taxonomy. The basic unit of classification is species, and it is further grouped into broader categories including genus, family, order, class, phylum, kingdom, and domain.

Let's analyze each option:

**a) Species:**
- Species is the most specific and fundamental unit of classification.
- It refers to a group of organisms that can reproduce and produce fertile offspring.
- Members of the same species share similar characteristics and can interbreed.
- Species is the lowest and most specific level of classification, making it less general in character compared to genus.

**b) Division:**
- Division is a higher taxonomic rank used in the classification of plants.
- It is equivalent to phylum in the classification of animals.
- Division is more general than species but less general than genus.
- It represents a group of related plant species that share common characteristics.

**c) Class:**
- Class is a higher taxonomic rank that represents a group of related orders.
- It is more general than division (in plants) or phylum (in animals).
- Class is a broader category than species and genus.
- It includes multiple species and genera that share certain common characteristics.

**d) Family:**
- Family is a higher taxonomic rank that represents a group of related genera.
- It is more general than class but less general than order.
- Family includes multiple genera and species that share certain common characteristics.
- It is a higher level of classification compared to species and genus.

Therefore, based on the hierarchy of classification, it can be concluded that species is less general in character as compared to genus.
