Total packets sent from A to E are ...
Minimum hop count from A to E is 3
1: A sends 2 packets B and C.
2: B sends 2 packets (C & D), C sends 2 packets (B & D).
3: C sends 2 packets (A & D), B sends 2 packets (A & D), D sends 2 packets (C & E), D sends 2 packets (B & E).
Total amount of packets = 2 · 7 = 14.
