If a protein that could be toxic to the expression host needs to be expressed in large quantities, then it is best to select an expression vector that
A) is not able to be replicated.
B) is inducible.
C) is attached to a normal cell promoter.
D) allows continual expression of the protein.

An inducible expression vector allows for tight control of protein expression in the host cell. This means that the toxic protein can be kept at low levels until induction is necessary, minimizing the potential harm to the host cell. The other options do not provide this level of control and may result in toxicity or decreased cell viability.
