A stone is dropped from the top of a tower of height \( h \). After 1 second another stone is dropped from the balcony \( 20 \mathrm{~m} \) below the top, both reach the bottom simultaneously. What is the value of \( h \) ?
a. \( 31.25 \mathrm{~m} \)
b. \( 100 \mathrm{~m} \)
c. \( 120 \mathrm{~m} \)
d. \( 130 \mathrm{~m} \)
