Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'symbiont-mediated suppression of host complement activation by complement sequestering'?

A. A process by which a symbiont prevents the activation of host complement by binding a soluble complement control protein (CCP) of the host and recruiting it to the microbe surface. The normal role of CCPs is to prevent complement activation on 'self' cellular targets. When soluble CCPs are recuited to the surface of a microbe, the complement fails to activate.
B. A process by which a symbiont prevents host complement activation by recruiting host proteases, destroying the complement before it has its effect on the symbiont.
C. A process by which a symbiont prevents host complement activation by sequestering it away from its surface.
D. A process by which a symbiont disrupts or prematurely activates host complement so that its microbial-destroying activities fail.

Answer: A process by which a symbiont prevents host complement activation by sequestering it away from its surface.
