C is the answers
Category 7 (Cat 7) cables provide the best performance with the least Electromagnetic Interference (EMI) due to their enhanced shielding. Cat 7 cables are designed to support higher speeds and bandwidth while reducing interference compared to Cat 5 or Cat 6.
Why Not A (Cat 5): Cat 5 cables have limited shielding and are prone to EMI, making them unsuitable for high-performance requirements.
Why Not B (Cat 6): Cat 6 offers better shielding than Cat 5 but less than Cat 7.
Why Not D (Coaxial): While coaxial cables are resistant to EMI, Cat 7 offers better performance overall for networking applications.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 3.1, cable types and their performance characteristics.
Cat 7 cables are less prone to interference due to several factors:
Shielding: Cat 7 cables use advanced shielding techniques, such as shielded twisted pair (STP) and foil shielding, to protect the signal from external electromagnetic interference. This helps to maintain signal integrity and reduce noise.
Alien Crosstalk: Cat 7 cables are designed to minimize alien crosstalk, which is interference between different cable pairs within a bundle. This reduces signal degradation and improves overall performance.
Higher Frequency Support: Cat 7 cables can support higher frequencies, which allows for faster data transmission rates. This can help to mitigate the effects of interference, as higher frequencies are less susceptible to noise.
By incorporating these features, Cat 7 cables offer superior performance and reliability compared to earlier generations of Ethernet cables.

While Cat 7 cables offer advanced shielding, other Cat cables also have varying levels of shielding. For example, Cat 5e and Cat 6 cables can be shielded or unshielded. Shielded cables are more resistant to interference but are also more expensive and difficult to install.
In general, Cat 7 cables offer the best combination of performance and interference protection, making them ideal for high-performance networks where signal integrity is critical. However, for most home and small office networks, Cat 6 or Cat 6a cables are sufficient.

Among the options provided, Cat 7 cable typically offers the best performance with the least electromagnetic interference (EMI).
