CorrectNot quiteAnswer C

Correct answer: C

Six measurements give five monthly gaps.
Total growth: $43 - 10 = 33$ cm.
Average: $33 \div 5 = 6.6$ cm per month.

Worth noting

5.5 cm divides by 6, the number of measurements; there are only 5 gaps between them. 6 cm is the middle monthly growth (the median), not the mean. 8.25 cm divides by 4.
