I believe this argument is inductive reasoning due to not using facts that support your sentence hope this helps :)
Most reading and writing is done by accessing words that your brain has stored. Your brain can process words at a super high speed, but it can’t process what it doesn’t know. That’s why knowing roots and affixes can be helpful because they give your brain a way to decipher unfamiliar words. That way, you can focus on the meaning<span> of texts and not just the words.</span>
A makes the most sense in this question :)
Your answer is A
Hope this helped!!
