Final answer:
The true statement about three different processors is that they can excel in different tasks due to varying architecture and specifications, not just clock speed.
Step-by-step explanation:
Considering three different processors, P1, P2, and P3, the correct statement is c) Different processors may excel in different tasks based on architecture and specifications. Processors cannot be universally ranked as 'faster' without context. The performance is influenced by various factors including, but not limited to, clock speed, core count, cache size, and the specific tasks they are performing. While clock speed does have an impact on performance, it is not the only factor; therefore, statement b is incorrect. Architecture and workload optimization can lead to a processor with a lower clock speed outperforming one with a higher clock speed in certain scenarios. Furthermore, without more information, we cannot verify that P1 is always faster than P2 and P3 (statement a) or that P2 and P3 are identical in every aspect (statement d).
