Explanation:

To solve this, we analyze each option:

• Option "Widely used, but found limited acceptance": Doesn't align with the historical context of Spearman's general mental capacity (g - factor) idea, which was quickly accepted and widely used in psychology for intelligence testing and theory.
• Option "Used only by followers of Spearman": Incorrect, as his ideas (like the g - factor) were adopted by many in the field of psychology, not just his followers.
• Option "Quickly accepted and widely used": Correct. Spearman's concept of a general mental capacity (the g - factor) was quickly accepted in the field of psychology and has been widely used in intelligence research, testing, and related areas.
• Option "Controversial even in his day": While there are later controversies and alternative theories, in his time, the idea of a general mental capacity (g - factor) was not highly controversial and was accepted relatively quickly.

Answer:

C. Quickly accepted and widely used. (Assuming the options are labeled A, B, C, D with A being "Widely used, but found limited acceptance", B being "Used only by followers of Spearman", C being "Quickly accepted and widely used", D being "Controversial even in his day")
