An embolus is what type of blood clot?

  1. Stationary

  2. Circulating

  3. Dissolving

  4. Expanding

The correct answer is: Circulating

An embolus is a type of blood clot that is circulating in the bloodstream. It differs from other types of blood clots in that it is not stationary (option A) or dissolving (option C). It also does not expand (option D) like other types of blood clots do. The term "embolus" specifically refers to a clot that has broken off from its initial location and is moving through the bloodstream. Therefore, the correct answer is B, circulating.
