In Spanish, 'Hola' means 'Hello' and 'cómo estás?' means 'How are you?'. The phrase 'Hola, ¿cómo estás?' is a common Spanish greeting. The other options incorrectly translate the Spanish phrase - 'Nice day' would be 'buen día', 'Where are you' would be '¿dónde estás?', and 'Come on' would be 'vamos' or 'vámonos'.
