Hi j_shreyans,

The word "Unlike" at the beginning of the sentence is a "trigger word" for a Comparison. So we must compare LIKE things and do so in Parallel format (if possible).

When dealing with a comparison, you have MUST be very strict with the wording that you use:

For example, you can compare….
A person to another person (or several people)
A person's idea to another person's idea (or several ideas)
A system to another system (or several systems)
The approach of a system to the approach of another system
Etc.

1) Comparison: The first part of the comparison is "a funded pension system", so we need the second part of the comparison to present something that is like a pension system. There's only one answer that matches. "A","C" and "D" mention an approach, "B" mentions the foundation - none of these are "a pension system"

Final Answer: E
