please help....question very urgent (it is multiple choice)

Suppose that I have 120 samples randomly shuffled. To perform 4-fold cross validation, I first partition the data into 4 sets:

Set 1 - Samples 1-30

Set 2 - Samples 31-60

Set 3 - Samples 61-90

Set 4 - Samples 91-120

Suppose that I used the r 2 as an evaluation metric. Now, I'm testing the performance of parameter value M = 3, and obtained the following results in validation:

Set 1 - 0.99

Set 2 - 0.5

Set 3 - 0.45

Set 4 - 0.4

(1) Does this result indicate possible bad partition of the data?

(2) Which performance value would be associated with validation performance for this 4-fold CV?

Group of answer choices

A. (1) Yes, (2) 0.585

B. (1) No, (2) 0.585

C. (1) Yes, (2) 0.99

D. (1) No, (2) 0.99

(1) Yes, (2) 0.4

(1) No, (2) 0.4
