Limited by and lack of?

Dear teachers,

I saw a sentence below from a transcript. (sources: https://singjupost.com/samsung-galaxy-s8-unpacked-2007-launch-event-full-transcript/)

• "We believe you shouldn’t be limited by expensive headsets or lack of access to great content."

How should I understand the aforementioned sentence between (a) and (b)?

• (a)
• We believe you shouldn’t be limited by expensive headsets.
• We believe you shouldn’t be lack of access to great content.

• (b)
• We believe you shouldn’t be limited by expensive headsets.
• We believe you shouldn’t be limited by lack of access to great content.

Thanks and best regards,

David Kim
