In a batch culture, the correct order of phases of growth follows a carefully mapped journey through time! It starts with the **lag phase**, where microorganisms acclimate and prepare for growth. This is followed by the **log phase**, where the population exponentially increases, hitting its peak performance. Next up is the **stationary phase**, where growth rates slow as resources deplete, and finally, the culture enters the **death/decline phase**, where cells die off due to unfavorable conditions. So, if you're picking the right order, it’s clearly **B)**: lag phase, log phase, stationary phase, death/decline phase! This sequence captures the typical microbial growth progression like a well-rehearsed performance!
