Step 1: Plan:
We have to sort four statements into true and false, and then read off the matching option. The false one is likely to be a statement that sounds soft about apartheid, since the system was harsh.
Step 2: Fact base:
Apartheid meant legal segregation by race. Black South Africans had no land rights, low wages, forced removals and no freedom to marry across the colour line.
Step 3: Statement A:
Harsh police action against protesters, with jail, torture and killings, is well recorded. So A holds.
Step 4: Statement B:
This one mixes a real fact with a false one. Land was denied, but marriage between races was forbidden by law, not allowed. So B fails.
Step 5: Statement C:
Black earnings were about a quarter of white earnings, as the textbook says. So C holds.
Step 6: Statement D:
Forced shifting of black people into poor homelands called Bantustans is a key feature of the system. So D holds.
Step 7: Read the options:
We need A, C and D without B. Only option 3 gives this combination, while the other three options all carry B or drop A.
Final Answer:
Option 3 matches the true statements. \[\boxed{3}\]
