D. Variant

Explanation

To answer the question, "The offspring from a cross between two individuals differing in at least one set of characters is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term used to describe the offspring resulting from a cross between two individuals that differ in at least one characteristic.

2. **Identifying the Options**: The options provided are:
- A) Polyploid
- B) Hybrid
- C) Mutant
- D) Variant

3. **Analyzing Each Option**:
- **Polyploid**: This term refers to cells that have more than two homologous sets of chromosomes. It does not specifically refer to offspring from a cross.
- **Hybrid**: This term refers to the offspring resulting from the cross of two different individuals, especially those that differ in at least one characteristic. Hybrids are typically heterozygous, meaning they possess two different alleles for a trait.
- **Mutant**: This term refers to an organism that has undergone mutation, resulting in new genetic variations. It does not specifically refer to the offspring from a cross.
- **Variant**: This term refers to a form that differs from the standard or original form in one or more characteristics. While it can relate to offspring, it is not specific to the offspring of a cross.

4. **Selecting the Correct Answer**: Based on the analysis, the correct answer is **B) Hybrid**, as it specifically refers to the offspring produced from the cross of two differing individuals.

### Final Answer:
The offspring from a cross between two individuals differing in at least one set of characters is called a **Hybrid**.
