**Question:**
Which of the following is 18:2Δ<sup>8,11</sup>?
### Description of Structures
Below is a series of six different fatty acid structures labeled A to F. Each structure is presented in a skeletal formula, which is a common way to represent organic molecules. These retain essential chemistry features (bonds and atoms) while simplifying complex organic molecules.
### Options:
- **A**: A structure with single and double bonds distributed along a hydrocarbon chain.
- **B**: A similar hydrocarbon chain with varying positions of double bonds.
- **C**: Another chain with different double bond positions.
- **D**: Comprised of both single and double bonds at unique locations.
- **E**: Features alternation in the placement of single and double bonds.
- **F**: Displays a distinctive arrangement of bond types along the chain.
### Objective:
The task involves identifying which of the given structures (A-F) corresponds to the fatty acid notation 18:2Δ<sup>8,11</sup>. This notation indicates a fatty acid with 18 carbon atoms, 2 double bonds at carbon positions 8 and 11.
**Instructions:**
Select the letter corresponding to the correct structure by analyzing the configuration of double bonds in each given structure.
