An arch construction provides because, the pieces that make up the arch apply force
a. (1) aesthetic appeal; (2) upwards towards the center
b. (1) stability; (2) down the sides
c. (1) suspension; (2) to the connected cables
d. (1) height; (2) to the shell

Option B

Explanation:

Arch is basically a bridge structure that is abutted at the ends and hence transfers  load or weight of itself and the other structures to the abutment which further pacify the loads by distributing it to the downwards structure meant to bear load. In this way an arch which is a compressive structure also distributes the load by counteracting the thrust of neighboring structure

Hence, option B is correct
