Explanation:
First, look at the CPU requirements for Exchange 2016.
"Exchange supports a virtual processor-to-logical processor ratio no greater than 2:1, although we
recommend a ratio of 1:1. For example, a dual processor system using quad core processors contains a
total of 8 logical processors in the host system. On a system with this configuration, don't allocate more
than a total of 16 virtual processors to all guest virtual machines combined."
Furthermore, the host operating system also needs 2 processors.

Host 1 uses 12 out of 20 cores
Host 2 uses 20 out of 20 cores
Host 3 uses 32 out of 20 cores
You need 12 cores, so Host 3 lacks the resources.
This leaves hosts 1 and 2.
Now, let's look to the memory requirements:
"...using dynamic memory or memory overcommit features for Exchange isn't supported."

Host 1 uses 20 out of 64 GB
Host 2 uses 48 out of 64 GB
Host 3 uses 44 out of 64 GB
You need 24 GB for each VM.
Only host 1 has the resources for it.
It is not recommended to put both VM's on one host.
So, the answer should be: A.
