B
clamshell samplers
C
piston corerspiston corers
D
drilling ships
Explanation: 

Detailed explanation-1: -Minerals contents in sediment are analysed mainly using three different method i.e. acid wash, optical and physical method.

Detailed explanation-2: -Several types of technology are used to collect marine sediments from research ships. These devices include surface samplers and sediment corers. Surface samplers collect only the uppermost layers of the ocean floor. These devices include dredges and benthic grabs.

Detailed explanation-3: -2. Sediments are also classified by origin. There are four types: lithogenous, hydrogenous, biogenous and cosmogenous. Lithogenous sediments come from land via rivers, ice, wind and other processes.

Detailed explanation-4: -Clamshell Sampler, Piston Corer, and Drilling Ships. To examine the past using stratigraphy, scientists study the sediment layers to look for clues in the rock composition, microfossils, and other physical properties.
