What are Mike Lazaridis and Jim Balsillie known for inventing?

The first cardiac pacemaker
The Canadarm
The Blackberry
Pioneering brain surgery

The correct answer is: The Blackberry

Mike Lazaridis and Jim Balsillie are both known for co-founding Research In Motion (now known as BlackBerry Limited), a Canadian company that developed and popularized the Blackberry smartphone. While the other options may have been significant advancements in their respective fields, they are not directly related to Mike Lazaridis and Jim Balsillie. Option A refers to a medical device invented by Canadian John Hopps, and option B refers to a robotic arm used on spacecraft developed by the Canadian Space Agency. Option D refers to a medical procedure, not an invention. Therefore, option C, the Blackberry, is the correct answer.
