Answer:
By combining similar instructions into groups which will then execute in parallel ( A )
Step-by-step explanation:
Instruction - level parallelism is a measure of how a computer program can execute different instructions found inside of it simultaneously, Instruction-level parallelism is different from concurrency because it talks about executing different instructions in a particular computer program simultaneously in parallelism. while concurrency is the execution of several instructions sequence from at the same time,this similar to instruction - level parallelism but it involves several process threads i.e it allows multiple users to run different transactions on a particular system as seen in a database.
