Which of the following substances is used as a Fumigant that ends with 'IDE'?

Methyl Bromide is a well-known fumigant that is utilized for its effectiveness in controlling various pests, including insects and rodents, in agricultural and structural settings. It is classified as a chemical fumigant and is particularly noted for its ability to penetrate materials and eradicate pests from sealed environments. The term "fumigant" refers to a substance that produces gaseous fumes to suffocate or poison pests in an enclosed space, making methyl bromide a suitable choice in this category, especially as it ends with the suffix 'IDE'.

In contrast, the other substances listed do not fit the criteria of a fumigant ending with 'IDE'. Chlorfenapyr is an insecticide, while Warfarin and Diphacinone are anticoagulant rodenticides typically used for controlling rat and mouse populations. Their use and application methods differ significantly from those of fumigants like methyl bromide, which specifically targets pest management through vapor action.
