I enjoyed the irony of starting your post with the word if...

The truth is we do not have to be greatly or vastly inconvenienced to follow the path set out by option A!

Many people undertaking small acts consciously could create a ripple effect of collective will, could destroy entire industries...Could create permanent and lasting change. i don't wanna fall into the cliche trap of using the word change in the manner that a politician does...

When campaigning to be elected, politicians promise change...A limp, sappy, half-assed change that doesn't really mean anything OR is an in-joke to their corrupt cronies. After all, crashing entire global financial markets every few years to exact what they euphemistically describe as a redistribution of wealth is change, right?

Climbing over the poorest people on the planet to reach your ends and skirting round the edges of genocide for profit is a plan that creates great change, right?

Consider this...lets create a fictional evil corporate behemoth to use as an example SonManto...cough ;)

If enough people start to boycott their evil farming chemicals and pesticides and seeds that the poorest on earth (who rely on farming for their very survival) can not afford without going into debt...What would happen to their profits, stock, evil empire?

Or brand x fizzy black drink filled with such noxious toxins as Aspartamane...What if parents taught the truth to their family, friends, colleagues, offspring about having a healthy lifestyle not one that takes us down the road to ill health and into the clutches of Big-Pharma? What would happen to that multi-billion dollar brand?

What if we looked to our so called leaders and said NO! Not in my name, en-masse? How do the few truly control the many?

I choose to start by attacking profits and ballot boxes...After that the whole house of cards is at best precarious.

If these individuals, corporate and otherwise truly existed, we would know them if we searched the information, right?

To make the decision that resistance is futile Is in my opinion, to refuse to make any decision at all.

In this hypothetical situation, none of the other answers are really answers at all!
