B. You can delete the main route table with the VPC and replace it with a custom route table
C.You can create additional custom route tables for your VPC
D.Each subnet in a VPC must be associated with a route table

Answer - B
The AWS documentation mentions the following on Route tables
The following are the basic things that you need to know about route tables:
· Your VPC has an implicit router.
· Your VPC automatically comes with a main route table that you can modify.
· You can create additional custom route tables for your VPC.· Each subnet must be associated with a route table, which controls the routing for the subnet. If you don`t explicitly associate a subnet with a particular route table, the subnet is implicitly associated with the main route table.
· You cannot delete the main route table, but you can replace the main route table with a custom table that you`ve created (so that this table is the default table each new subnet is associated with).
