A
LB broth
B
EMB broth
C
YED extract
D

Explanation: 

Detailed explanation-1: -E. coli is able to grow on a wide range of carbon sources, but is typically grown in a rich medium, such as Luria-Bertani broth, or on rich media agar plates (see Reagents and Solutions for recipes or APPENDIX 4A for protocols describing the preparation of commonly used liquid and solid media).

Detailed explanation-2: -The agar form of the medium should be designated LA but it is often referred to as LB. Although originally developed for bacteriophage studies and Shigellagrowth, LB subsequently became the medium of choice for growth of Escherichia coli and other related enteric species.

Detailed explanation-3: -LB Broth is one of the most referenced bacterial media for cultivating and maintaining Escherichia coli (E. coli) strains. Our LB Broth is based on the Lennox formulation, one of the most commonly used formulations for LB medium.
