Two investment managers disagree over whether to trust Goldman Sachs. Goldman Sachs has been called a "giant vampire squid wrapped around the face of humanity, relentlessly jamming its blood funnel into anything that smells like money." One manager has received good advice from the firm. The other has caught the firm salesmen using tricks on three separate occasions. Their disagreement is .a. essential
b. emotional
c. substantive

Option C  

Explanation:

Simply put, if the discrepancy or disagreement is only about sharing conflicting views about evidence or subscribing to opposing beliefs, then the conflict in dispute is known as a substantive conflict or disagreement.
