options:
c. stratified
a. cluster
b. systematic
d. random

Explanation:

In sampling methods, random sampling uses a computer or other means to generate random numbers to select samples. Here, the pollster generates 900 random numbers to choose telephone numbers, which matches the random sampling method. Stratified sampling divides the population into strata first, cluster sampling divides into clusters, and systematic sampling selects at regular intervals, none of which apply here.

Answer:

d. Random
