Answer :
Final answer:
The Broca area's impairment due to a stroke affects the ability to pronounce words, leading to difficulties in producing speech effectively but generally leaving the understanding of language intact. Therefore option b) Ability to pronounce words is the correct.
Explanation:
If the Broca area were affected by a stroke, the ability to pronounce words would be affected. The Broca's area is responsible for speech production, specifically in forming words and sentences in a fluent and coherent manner. Damage to this area, often resulting in a condition known as Broca's aphasia, would impair a person's ability to produce speech effectively. Although individuals with this condition can generally understand spoken language, they struggle with speaking it, leading to halting, effortful, and often grammatically incorrect speech. This contrasts with damage to Wernicke's area, which affects the ability to understand spoken and written language, resulting in speech that is fluent but nonsensical.
