Final answer:
The historically low internet use in Kenya is due to a lack of infrastructure, a factor contributing to the digital divide.
Step-by-step explanation:
Historically low internet use in Kenya has been largely due to a lack of infrastructure. This challenge is a facet of the broader digital divide issue, which affects regions that have not received infrastructure upgrades facilitating high-speed internet access. While the mobile phone accessibility has significantly increased in Sub-Saharan Africa, traditional internet infrastructure remains deficient, impacting access to digital media and the opportunities and information it provides. Affluent urban and suburban areas often receive priority for such upgrades, leaving rural and low-income regions with limited connectivity. Thus, the correct answer to the student's question is Option 3: c. infrastructure.
