Glacial ice can transport rocks as big as a house. It has very high transport competence and moves very slowly across a very large distance.
The maximum size of particles that a stream can transport is defined as stream competence. This is a concept under hydrology. Streams depending on its velocity can carry sand, mud, silt and cobble along with the dissolved and suspended load.
The process by which Ocean waves transport sediments, large pebbles and boulders is referred to as Coastal Transportation. During Coastal transportation, large pebbles and boulders are rolled along the seabottom, while beach material is bounced along the seabed.

Suppose that you develop the following hypothesis: Some floods in rivers have enough energy to carry large clasts, i.e., particl

Answer:

b. stratigraphically alternating sequences of sandstones, conglomerates, and shales.

Explanation:

It is unlikely that one would find igneous rocks such as basalt and granite in fluvial environments. Coal is also not usually found in fluvial environments. Limestone prefers shallow and calm waters so would not be moved by water normally. This therefore invalidates options a, c, d, e and f.

For the hypothesis to be true, one would need to find conglomerates as these contain large clasts and are present in fluvial environments. Alternating sequences involving conglomerates and sandstones would indeed show that that some floods were able to carry large clasts.
