How could you modify the following query in order to ONLY count customers with a $$rst$\_$name starting with $"$T$"?$

SELECT c$.$last$\_$name, c$.$first$\_$name, COUNT$($o$.$orderNumber$)$

FROM customers c LEFT JOIN orders o ON c$.$customer$\_$id $=$ o$.$customer$\_$id

GROUP BY c$.$customer$\_$id;

Group of answer choices

Use a WHERE clause at the end of the query.

Use a HAVING clause before the GROUP BY$.$

This cannot be done.

Use a WHERE clause before the GROUP BY$.$
