How do you instantiate a TopologyTestDriver in Java for a given topology and properties?

Anew TopologyTestDriver(props, topology);

BTopologyTestDriver.create(topology, props);

CTopologyTestDriver.build(topology, props);

Dnew TopologyTestDriver(topology, props);

Step-by-Step Solution

Solution:

Step 1: Recall constructor signature
The TopologyTestDriver is instantiated using its constructor with parameters: topology and properties.
Step 2: Analyze options
new TopologyTestDriver(topology, props); matches the correct constructor call. Options B and C use non-existent static methods. new TopologyTestDriver(props, topology); reverses the parameter order, which is incorrect.
Final Answer:
new TopologyTestDriver(topology, props); -> Option D
Quick Check:
Constructor with (topology, props) [OK]

Quick Trick: Use constructor with topology and props [OK]
