Step-by-step explanation:
The ExpressCard /54 form factor is characterized by its width at the connector, which is 54mm. This design allows for compatibility with both ExpressCard /34 and /54 slots, providing flexibility for various devices. The ExpressCard interface replaced the PC Card (PCMCIA) standard and is commonly used for expansion cards in laptops.
Unlike the square shape of its predecessor, the PC Card, the ExpressCard has a unique design, and it is not L-shaped. Additionally, the width at the connector is 34mm for the ExpressCard /34 variant. The ExpressCard technology was developed to offer faster data transfer rates and improved performance compared to the older PC Card standard.
Therefore, correct answer is c) 54mm wide at the connector
