To 'play havoc' with something means to:

To "play havoc" with something means to cause significant disruption, chaos, or damage. This phrase conveys the idea of things being thrown into confusion or being severely impaired, which aligns perfectly with the meaning of ruining something. For instance, if a storm were to "play havoc" with a community, it would suggest that the storm has caused extensive damage or interference in normal operations.

The other choices, which imply enhancing, improving, or maintaining, do not capture the essence of disruption and disorder that "playing havoc" entails. They suggest positive or stable outcomes, which are contrary to the chaos implied by the correct interpretation. Thus, the phrase's connotation strongly supports the understanding that it is associated with ruining or significantly impairing something.
