E Correct answer
Explanation

All 1, 2 and 3. Bacterial DNA replication by: Rolling Circle- multiple copies of a single circular DNA is achieved. Bi-directional- the synthesis of DNA is done in two directions; and Theta mode- it a type of bi directional replication, where “theta” (Θ) type structure is formed.
