Fill in the blank with the most suitable word.

In addition, it is believed they possess crude electronic devices capable of triggering ______ bombs.

incendiary

The most suitable word to fill in the blank is incendiary.

• Intelligible means able to be understood. It does not make sense in the context of the sentence because bombs are not capable of being intelligible.
• Insipid means lacking in flavor or interest. It does not make sense in the context of the sentence because bombs are not insipid.
• Inflammatory means likely to cause anger or excitement. It is a close match to the word incendiary, but it is not the most appropriate word because it does not specifically refer to bombs.
• Insensible means not able to feel or perceive things. It does not make sense in the context of the sentence because bombs are not insensible.
