Given:
- Average age of 34 boys = 14 years
- Average age of 34 boys and teacher = 15 years

To find:
- Teacher's age

Solution:
Let the teacher's age be x.
Total age of 34 boys = 34 * 14 = 476
Total age of 34 boys and the teacher = 35 * 15 = 525 (as there are 35 people now)
Teacher's age = Total age of 35 people - Total age of 34 boys
x = 525 - 476
x = 49

Therefore, the teacher's age is 49 years.

Answer: Option (c) 49 years.
