On the basis of the network provided in the exhibit， all routers are configured to run EIGRP on all links. If the link between PG-R1 and PG-R2 fails， what is the maximum number of queries PG-R3 will receive for 192.168.1.0/24， assuming that all the packets sent during convergence are transmitted once （there are no dropped or retransmitted packets）？（）

A.PG-R3 will receive up to four queries for 192.168.1.0/24， one each from PG-R2， PG-R4， PGR5，and PG-R6.
B.PG-R3 will receive up eight queries for 192.168.1.0/24， one from PG-R2， two from PG-R4，three from PG-R5， and four from PG-R6.
C.PG-R3 will receive one query for 192.168.1.0/24， since the remote routers， PG-R4， PG-R5， and PG-R6， are natural stubs in EIGRP
D.PG-R3 will not receive any queries from PG-R2， because there are no alternate paths for 192.168.1.0/24.
