Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
A - "to" is missing for the first two actions B - "to" is missing for the third action C - "then corral them" - then is not necessary E - "to" is missing for the last action
Though I am not happy with the not using "to" at all in D, other places wherever "to" is used, is used wrongly. So I would assume it is okay not to use "to" at all.
"To" may be left out in similar cases only in informal speech, otherwise it's mandatory. Therefore, A, C, and D are immediately out. E is wrong because leaving the cattle alone, corralling them, driving them to market are three distinct actions, not "the only thing." Besides, active voice is always preferable to passive voice. B is concise and grammatically correct.
P.S. "To" is not missing for the third action; it's right there, in the part that's constant.
