A binary file stores a list of companys salaries. Each salary is stored as float. Which code fragment below will read the third salary of the file into a variable sal. The file is already opened using the file description fid.

a. fseek(fid, 0, SEEK_SET);

fread(&sal, sizeof(double), 1, fid);

b. fseek(fid, 0, SEEK_END);

rc = ftell(fid);

fseek(fid, rc - 3*sizeof(double), SEEK_END);

fread(&sal, sizeof(double), 1, fid);

c. fseek(fid, 0, SEEK_SET);

rc = ftell(fid);

fseek(fid, rc - 2*sizeof(double), SEEK_CUR);

fread(&sal, sizeof(double), 1, fid);

d. fseek(fid, 0, SEEK_SET);

fseek(fid, 2*sizeof(double), SEEK_CUR);

fread(&sal, sizeof(double), 1, fid);

e. None of the above
