A solid core transformer is represented by a specific symbol in electrical schematics, which typically incorporates the design indicating a core made from a solid material, as opposed to a laminated or air core. In the context of transformer symbols, the correct option visually conveys the essential structural component of the transformer that allows it to function effectively.

In this case, the indicated symbol not only reflects the physical characteristics of a solid core but also aligns with standardized electrical schematic practices. This helps anyone reading the schematic easily identify the element being depicted and understand its role within the circuit.

While other symbols may represent different types of electrical components or transformers, it is the distinct representation of a solid core in the chosen answer that is crucial for clarity and accurate understanding in circuit designs.
