Final answer:
The presentation layer in the OSI model is responsible for data format conversion, encryption, decryption, and compression, enabling interoperability among different systems.
Step-by-step explanation:
The layer in the OSI reference model responsible for converting data so that systems using different data formats can exchange information is the c) Presentation layer. This layer serves as the translator for the network. It is responsible for data encryption and decryption, data compression, and transforming data into the proper format for network transmission. This allows devices and applications on the network to interpret the data correctly, regardless of any underlying differences in data representation.
