Concept:After verbs of perception (see, hear, watch, feel) the pattern is: verb + object + bare infinitive (or + -ing form).Solution:"Dauda saw the thief run out of the shop." ("saw the thief running" would also be correct, but it is not an option.)"Was running", "is running" and "ran" are finite verbs; they cannot follow the object of saw in this pattern.Answer:Option C (run)
