A website will run on EC2 instances behind an Application Load Balancer. You will manage DNS with Route 53. Which Route 53 record type should you use to point the zone apex (for example, company.com) to the ALB?

You should use an ALIAS record to point a zone apex (like company.com) to an AWS resource such as an Application Load Balancer (ALB). ALIAS records are a Route 53-specific extension that functions like a CNAME but can be used at the zone apex, which is not possible with standard CNAME records. CNAME records cannot be used at the zone apex because they would conflict with other required records like SOA and NS records. SOA (Start of Authority) and TXT (text) records serve different purposes: SOA records provide authoritative information about the zone, and TXT records store arbitrary text data.
