Which two command can you enter to display the current time sources statistics on devices? (Choose TWO)

Question:
Which two command can you enter to display the current time sources statistics on devices? (Choose two)

• Show ntp associations.
• Show clock details.
• Show clock.
• Show time.
• Show ntp status.

Explanation: Maybe the “current time sources” here mention about the status of the clock source. In the below output, the “show ntp associations” command reveals the IP address of the clock source (which is 209.65.200.226), the stratum (st) of this reference clock…

R1#show ntp associations
      address         ref clock     st  when  poll reach  delay  offset    disp
*~10.1.2.1         209.65.200.226    9   509    64  200    32.2   15.44  16000.
 * master (synced), # master (unsynced), + selected, - candidate, ~ configured

Below is the output of the “show ntp status” command. From this output we learn that R1 has a stratum of 10 and it is getting clock from 10.1.2.1.

R1#show ntp status
Clock is synchronized, stratum 10, reference is 10.1.2.1
nominal freq is 250.0000 Hz, actual freq is 249.9987 Hz, precision is 2**18
reference time is D5E492E9.98ACB4CF (13:00:25.596 CST Wed Sep 18 2013)
clock offset is 15.4356 msec, root delay is 52.17 msec
root dispersion is 67.61 msec, peer dispersion is 28.12 msec

In fact this question is unclear, but other answers are surely not correct.
