Concept:Find the total number of goals by multiplying each goal count by the number of teams that scored it, then adding all the products.Explanation:For each goal value $x$, use its frequency $f$ and calculate $fx$.$0 \times 4 = 0$$1 \times 3 = 3$$2 \times 15 = 30$$3 \times 16 = 48$$4 \times 1 = 4$$5 \times 0 = 0$$6 \times 1 = 6$Add all the $fx$ values to get the total goals:$0 + 3 + 30 + 48 + 4 + 0 + 6 = 91$The frequencies sum to $40$ teams, so the recorded data is consistent.Answer:The total number of goals scored is $91$, which is option C.
