Give answer in seconds (unit)

Crosvolidotion is an important step in machine learning for hyperparameter tuning. Let's say you are tuning two hyperparameters (one has 10 candidate values and the other has 5 candidate values in a learning model) by using 10 -fold cross validation. The training time taken by running the learning algorithm once is 10 seconds and the test tome on one fold is 2 seconds. Which of the followings is the correct overall execution time for 10 -fold cross validation in searching for the optimal hyperparameter values
