To supply a 24volt output with a transformer with a 5:1 turns ratio, the input required is
- 4.8
- 24V.
- 120V.
Explanation from PART66Online
A 5:1 step-down ratio means the input is five times the output, so to supply 24 V the primary needs 5 x 24 = 120 V. The 4.8 figure divides instead of multiplying, and 24 V would imply a 1:1 ratio with no transformation at all.

The ratio is 5:1, therefore you need an input which is 5 times greater than the output. Thus, the correct answer is 120v because 120v= 5*24
