Answer

To solve the question regarding which taxonomic rank generally ends in `aceae`, we can follow these steps:

### Step 1: Understand the Taxonomic Ranks
In biological classification, organisms are categorized into various hierarchical ranks. The main taxonomic ranks include Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.

### Step 2: Identify the Suffix `aceae`
The question specifically asks for a taxonomic rank that ends with the suffix `aceae`. We need to recall which of the taxonomic ranks typically uses this suffix.

### Step 3: Analyze the Options
We have four options to consider:
1. Family
2. Genus
3. Order
4. Class

### Step 4: Recall Taxonomic Naming Conventions
- **Family**: In plant taxonomy, the family rank often ends with `aceae`. For example, the family Solanaceae includes plants like tomato and potato.
- **Genus**: This rank does not have a specific suffix like `aceae`.
- **Order**: This rank also does not end with `aceae`.
- **Class**: Similar to genus and order, class does not end with `aceae`.

### Step 5: Conclusion
From the analysis, it is clear that the taxonomic rank that generally ends in `aceae` is **Family**.

### Final Answer
The correct answer is **Family**.
