The question seems to be asking which among the listed options can be considered as alternative solutions for an information system. Here's a step-by-step analysis of each option:

a. PC based solutions only - This could be a viable solution depending on the specific needs of the system. However, it's not the only solution as there are other types of systems that could also be effective.

b. An improved manual system - This could also be a potential solution. Improving a manual system could involve making processes more efficient or reducing errors. However, it may not be the most efficient or effective solution for all types of information systems.

c. Only client-server based solutions as they are popular now-a-days - While client-server based solutions are indeed popular and can be very effective, they are not the only possible solution. Other types of systems may also be suitable depending on the specific needs and circumstances.

d. Whatever management decides - While management's decision is important, it's not the only factor to consider. The most effective solution should also take into account the specific needs of the system, the available resources, and the potential impact on users and other stakeholders.

So, the answer to the question would be that one may consider all of the above as alternative solutions for an information system, depending on the specific needs and circumstances.
