Answer:
El sr. landrau tiene los ojos marrones.
Step-by-step explanation:
'Ojos' is plural for 'ojo' which means eye. The word 'the' in spanish can be plural (los) or singular (el). 'Marrón' (meaning brown) can be singular or plural (marrones). Since 'ojos' is plural, then you have to use the plural version of the other two words, 'los' and 'marrones'.
