Removing obstacles to success and opening up opportunities (e. g., giving scholarships to college) would be one logical implication of which delinquency theory?

The correct answer is strain theory. 

Strain theory is a theory by the sociologist, Robert Merton. According to this theory, crime and delinquency occur because of the pressure in society achieve coveted goals (such as being wealthy, possessing luxury items, obtaining a university degree, etc.) Merton argued that individuals who are less privileged and cannot afford the means to achieve coveted goals engage in acts of delinquency in order to do so. Removing obstacles to success and opening up opportunities is thus one logical implication of the strain theory.
