IMO, B is correct.
ANALYZE THE STIMULUS:
Fact: product sales declined several years. ==> NutriShake changed the marketing strategy
Fact: Old Strategy: focus on search engine optimization ==> Purpose: customers will purchase products DIRECTLY on Nutrishake website after they use searching tools
Fact: New Strategy: focus on referral networks, such as business social network ==> Purpose: customers will purchase products INDIRECTLY via intermediate websites
Fact: Product sales increased
Conclusion: The marketing strategy change (new strategy) improved product sales

How can you infer so much pqhai?
We are not able to connect the first strategy to the direct purchase of the product from the site; and the second strategy to the indirect purchase.
The text does not say anything about this difference, hence we cannot "make it up". The passage does not take into consideration the difference direct/indirect purchase, it does not mention it at all: both strategies could be based or not on it (we cannot say).
