Step 1: Understanding the Question:
This question tests knowledge of the history of cell biology.
Step 2: Detailed Explanation:
Carl Benda gave the name "mitochondria" in 1898.
He observed these organelles and named them (mitos = thread, chondros = granule).
Richard Altman (A): Observed mitochondria (called bioblasts).
Andreas Schimper (C): Coined the term "chloroplast".
