Answer:
c. User applications usually communicate directly with a device driver.
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem. Thus, it's a computer program or application that comprises of sets of code for performing specific tasks on the system.
The four (4) input-output (I/O) software layers includes the following;
I. Interrupt drivers (handlers): it is responsible for handling interruptions that occur while using a software on a computer system.
II. Device drivers: it controls the input-output (I/O) devices that are connected to a computer system through a wired or wireless connection.
III. Device-independent OS software: it allows for uniform interfacing and buffering for device drivers.
IV. User level software: it provides user programs with a simple user interface to perform input and output functions.
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Hence, user (software) applications make a request to the operating system (OS) to use a device and then the operating system (OS) communicates with the device driver.
In conclusion, user applications do not communicate directly with a device driver.
Sentences can be formed by phrases or clauses, in this case the italicized words are a phrase. A phrase is a grammatical unit composed by a set of words without subject and predicate whereas a clause is a grammatical unit formed by a set of words that includes a subject and a predicate.
The noun phrase “Wishing to be heard” is modifying the noun “speaker” since it is providing an explanation of why the subject is performing an action.

Hello :)
I'm inferring that the answer is C because in the passage it states "I held on to my unforgiveness in the hopes that by drinking this poison I might kill my enemy." basically stating that she was holding a grudge against this person and she hoped that it would hurt them, then she proceeded on stating "But soon it was my insides that were burning.". metaphorically speaking her insides weren't actually hurting from any "poison", she is basically saying that she was the only one who was hurting from holding this grudge. I'm inferring that it is C because that answers makes the most sense.
