Tracing the chosen Minotaur-class preliminary design

Which preliminary design became the 1906 Minotaur class?

Probably the third of seven, but the answer is explicitly tentative and should be checked against specialist books or archival plans.

The recalled answer is tentative: the third of seven preliminary designs is thought to have led to the 1906 Minotaur class, but the identification is not offered as certain. The design history is precise enough that checking a specialist source matters more than guessing from the finished ships. Norman Friedman's work on Victorian cruisers and Conrad Dixon's work on the Victorian Navy are suggested as likely starting points. Archival plans may still be needed for a definitive answer.
