From the output above, we see the local router is the active HSRP router with priority 110 while the default priority is 100 -> Answer D is not correct.
From the line "Standby router is 10.0.3.242, priority 100", we learn that standby router is configured with default priority -> Answer B is correct.
HSRP default hello and hold timers are 3 seconds and 10 seconds, respectively so answer A is correct.
