Final answer:
The correct answer is option (c). Emperor Nero was responsible for introducing sophisticated concrete construction into Rome with the construction of his Domus Aurea, or Golden House, after the great fire of 64 CE.
Step-by-step explanation:
The emperor who introduced sophisticated concrete construction into Rome with his Golden House was Nero. After a great fire ravaged Rome in 64 CE, Nero seized the opportunity to build the Domus Aurea, or Golden House, which was a grand villa that showcased the architectural revolution in Rome.
The architects, Severus and Celer, extensively used concrete, including innovations such as barrel vaults and domes, to create not just a new aesthetic in Roman architecture but also to expand the use of concrete in grand design.
Although Nero began the trend, later emperors and architects continued to develop and push the possibilities of concrete in structures like the Colosseum, the Markets of Trajan, and the Pantheon, adding to Rome's legacy of architectural innovation.
