The correct answer is: B. far-reaching.

A dynamic speech by the Prime Minister can have far-reaching repercussions abroad. This means that the speech can have a significant impact on other countries, even if it is not directly addressed to them. For example, if the Prime Minister speaks out against a particular policy or action by another country, this could lead to that country taking retaliatory measures. Alternatively, if the Prime Minister speaks in support of a particular cause, this could encourage other countries to follow suit.

The other options are incorrect for the following reasons:

  • A. recriminations are accusations or complaints made against someone. This is not the most likely outcome of a dynamic speech by the Prime Minister.
  • C. consequence is a result or effect of something. This is a more general term than "far-reaching", and it does not necessarily imply that the consequences of a speech will be significant.
  • D. gesticulations are movements of the hands and arms, especially when speaking. This is not something that is typically associated with dynamic speeches.
