Suggested answer: A, D
Explanation:

According to the trace options output in the exhibit, the following statements are correct:

This packet is part of an existing session. This is indicated by the line flow session id 0x00000000, hash 0x00000000, table 0x00000000, flow process exit, which shows that the packet matches an existing session entry in the flow table1.

The SRX device is changing the destination address on this packet from 10.0.1.1 to 172.20.101.10. This is indicated by the line nat: translated 10.0.1.1->172.20.101.10, which shows that the packet undergoes destination NAT2.

The following statements are incorrect:

The SRX device is changing the source address on this packet. There is no indication of source NAT in the trace options output2.

This is the first packet in the session. The first packet in a session would have a different trace options output, which would include the line flow_first_inline_processing and show the creation of a new session entry in the flow table1.
