Final answer:
Protestants who disagreed with the Elizabethan Settlement's compromise called it 'The Middling Way'. This term reflected their dissatisfaction with the middle-ground approach between Roman Catholicism and Protestantism.
Step-by-step explanation:
The Protestants who refused to accept the religious compromise of the Elizabethan Settlement referred to it as d) The Middling Way.

However, for those who were staunchly Protestant, they found the Settlement too middle-ground and an unsatisfactory resolution of the fierce religious divide of the times.
