Given the task definition and input, reply with output. You are given a paragraph, a question and some answer options (associated with "A", "B", "C", "D", etc.) You need to list all the correct answer options with their associated letters (e.g. "A" can be a valid answer). Note that sometimes, more than one option can answer the question correctly and completely. In those cases, please generate all such options separated by a comma (e.g. "A, B" is a valid answer). Do not generate anything else apart from one or more of the following characters: 'A', 'B, 'C', 'D', etc.

Paragraph- Sent 1: Water flowing over Earths surface or underground causes erosion and deposition.
Sent 2: Water flowing over a steeper slope moves faster and causes more erosion.
Sent 3: How water transports particles depends on their size.
Sent 4: When water slows down, it starts depositing sediment.
Sent 5: This process starts with the largest particles first.
Sent 6: Runoff erodes the land after a heavy rain.
Sent 7: It picks up sediment.
Sent 8: Runoff carries most of the sediment to bodies of water.
Sent 9: Mountain streams erode narrow, V-shaped valleys and waterfalls.
Sent 10: Erosion and deposition by slow-flowing rivers create broad floodplains and meanders.
Sent 11: Deposition by streams and rivers may form alluvial fans and deltas.
Sent 12: Floodwaters may deposit natural levees.
Sent 13: Erosion and deposition by groundwater can form caves and sinkholes.
Sent 14: Stalactites and stalagmites are mineral deposits.
Sent 15: They build up in caves as water continues to drip. 
Question: Which particles are deposited first when water flowing over Earth's surface begins to slow down? (A) Mineral deposits (B) Size (C) Water (D) Stalagmites (E) Largest (F) Smallest (G) Heavy particles (H) Stalactites (I) Sediment (J) The largest particles.
