For the two similar voting groups in Welland to gain power, it would make sense to:

The option that suggests creating an alliance with the libertarians is a strategic move for the two similar voting groups in Welland. This approach allows the groups to pool their resources, share voter bases, and strengthen their collective influence in the political arena. By forming an alliance, they can encourage collaboration on shared goals, enhance their visibility, and potentially attract undecided voters or those who traditionally lean toward libertarian ideologies.

Combining forces can lead to a stronger candidate or a unified platform, making it more advantageous when competing against larger or established political entities. In this context, the alliance serves to consolidate support, which is a fundamental strategy in electoral politics, especially for groups that may otherwise be fragmented and weaker on their own.

The other options would either complicate the political landscape or dilute their voting power rather than enhance it. For example, adding a sixth party may create confusion and fragment the vote further, while having less votes is counterproductive to gaining power. Combining conservative parties could be beneficial in some contexts, but if the two groups in question are already similar in ideology, aligning with a distinctly different party such as the libertarians may offer a fresh approach and broader appeal.
