Explanation:

FORTRAN (Formula Translation) was one of the earliest high-level programming languages, specifically designed for numerical computation and scientific computing. It excels at complex mathematical and scientific calculations. Therefore, statement B, 'Carrying out mathematics computations,' is precisely what FORTRAN *is* used for. Conversely, FORTRAN was not primarily designed for graphics or 'drawing pictures' (statement A). While modern FORTRAN compilers and libraries might offer some graphical capabilities, its core purpose and historical strength do not lie in graphics rendering. The question asks what FORTRAN is *not* used for. Since it is not primarily used for drawing pictures (A), but is used for mathematics computations (B), the correct answer is 'Only A'.
