What is the best match?

TDY

    { 1 } - differentiate at seven weeks in embryonic development if the Y chromosome is present
    { 2 } - sexual ducts that are present in all embryos but that develop into male structures (epidydimis and vas deferens) if the Y chromosome is present
    { 3 } - testicular determinant Y
    { 4 } - the presence or absence of which in the one cell zygote that biological determination of sex depends on
    { 5 } - are destroyed if the Y chromosome is present in the embryo

3 is correct!

TDY

    { 1 } - differentiate at seven weeks in embryonic development if the Y chromosome is present
    { 2 } - sexual ducts that are present in all embryos but that develop into male structures (epidydimis and vas deferens) if the Y chromosome is present
    { 3 } - testicular determinant Y
    { 4 } - the presence or absence of which in the one cell zygote that biological determination of sex depends on
    { 5 } - are destroyed if the Y chromosome is present in the embryo

TDY <=> testicular determinant Y
