All Are Steps in the Sequence for Construction of a Chimeric

All are steps in the sequence for construction of a chimeric plasmid EXCEPT:

A) annealing the ends of the vector and foreign DNA.
B) cutting the source of the foreign DNA with a restriction endonuclease.
C) reannealing the ends of the vector back together.
D) cutting the vector plasmid with the same restriction endonuclease.
E) none of the above.
