b. the quote contradicts the author’s argument.
c. the quote comes at the beginning of the paragraph.
d. the quote is not from reliable source material.

Explanation:

The source cited is "Mikel Rollah, director of Veganism Now!" which is an advocacy group for veganism, not an independent, peer-reviewed, or neutral expert source for nutritional claims. Such a source has an inherent bias, making it unreliable for objective factual statements about diet nutrition.

Answer:

D. The quote is not from reliable source material.
