Answer:
Option A
Explanation:
A series of intermeshing gears is called a gear train.
Intermeshing gears turn in opposing directions.
In a gear train we have a gear known as the driver and one known as the follower.
Driver - is the gear that has the force or motion input.
Follower - is the gear that results in the force or motion output.
It may be noted that when the number of intermediate gears are odd, the motion of both the gears (i.e. driver and driven or follower) is in the same direction.
But if the number of intermediate gears are even, the motion of the driven or follower will be in the opposite direction of the driver

I'd say D: Wrong, because transporting information is what a network does, and the Transport Layer is at the heart of that layer.
Transport layer is truly at the heart of the OSI model. Its main function is to transfer application data from the source to destination. This layer provides a reliable end-to-end communication service and transfers data for the user layers above it, as well as shielding the rest of the layers below from details like message error and flow control functions. If packets get destroyed or lost during transmission, it is in the best interest of Megan to check the transport layer. Transport layer ensures that whenever something like this happens, packets must be re-transmitted.
