The two nations that competed to include Siam (present-day Thailand) in their sphere of influence were A. Great Britain and Italy.

To find the answer to this question, we need to understand the term "sphere of influence" and identify the countries involved in the competition.

A sphere of influence refers to a region or country where one or more larger powers have indirect control and influence over the economic, political, or military affairs. In the context of the question, we are looking for the two nations that vied for control over Siam (present-day Thailand).

To determine which nations competed for Siam, we can analyze the given options:

A. Great Britain and Italy: This option doesn't include any mention of the Netherlands, so it doesn't fit the criteria.

B. Netherlands and Great Britain: This option includes both the Netherlands and Great Britain, so it is a potential answer.

C. Netherlands and Great Britain: This option is a duplicate of the previous option, so it can be ignored.

D. Italy and Ethiopia: This option mentions Italy and Ethiopia, but it doesn't include the Netherlands, so it is not relevant to the question.

Based on the analysis, the correct answer is B. Netherlands and Great Britain, as they were the two nations competing to include Siam in their sphere of influence.
