Answer: Le gusta mucho la casa.
Explanation: Ricardo says:
"The house is lovely and it's perfect for my family. The neighborhood is clean and safe, and the architectonic style is interesting"
The options (In English) are:
"I like a lot the houses" - Me gustan mucho las casas.
"he doesn't like a lot the houses" - No les gusta mucho la casa.
"nobody likes the house" - A nadie le gusta la casa.
"He likes the house" - Le gusta mucho la casa.
In the sentence he says that he likes that particular house, so the right option is the fourth one.
