Which type of firearm was developed first among the following?

The matchlock firearm was indeed the first type developed among the options provided. Introduced in the 15th century, the matchlock mechanism utilized a simple match (a slow-burning cord) that was held in a clamp and brought into contact with the gunpowder when the trigger was pulled. This innovation marked a significant advancement from previous means of ignition, as it allowed for a more reliable and consistent method of firing a gun.

The flintlock, percussion cap, and wheel lock mechanisms came later, each offering improvements in ignition reliability and efficiency. The flintlock system, developed in the early 17th century, replaced the match with a piece of flint that struck steel to create a spark. The wheel lock, invented in the late 15th century, used a spinning wheel to create a spark, and the percussion cap system, introduced in the early 19th century, utilized a small cap containing explosive material to ignite the gunpowder.

Understanding this development timeline helps clarify the advancements in firearm technology over the centuries.
