The notation F1F1F1S1F1F1F10 represents a matrix with 3 rows and 10 columns where the entries are real numbers. So the size of the matrix is 2 F1F1F1S1F1F1F10. 
To identify the entry located in the second row and first column, we look for the element in the second row (since the matrix has two rows) and first column (since the matrix has 10 columns) which is 3; 6. So the answer is choice B.
