Emma's scarf is currently 4 inches long and she knits 3 3/4 inches per minute.
Let's calculate how long Emma's scarf will be after 7 minutes:
4 inches + 7 minutes x 3 3/4 inches = 4 + 26 1/4 = 30 1/4 inches
After 7 minutes, Emma's scarf will be longer than Tish's scarf, which is currently 17.7 inches long.
Therefore, the correct answer is:
