Final answer:
The D+ meson, with a charm of +1 and zero baryon number, strangeness, topness, and bottomness, is made up of a charm quark and an up quark paired with a down antiquark (c\( \overline{d} \)). The quark configuration of a D+ meson is c+u+d. option B
Step-by-step explanation:
The D+ meson, characterized by a single positive charge and a charm of +1, with zero baryon number, strangeness, topness, and bottomness, is composed of charm (c) and up (u) quarks in combination with a down antiquark (\( \overline{d} \)). The correct quark configuration for the D+ meson is c\( \overline{d} \), indicating that it contains charm and up quarks, with the presence of a down antiquark as well.
The quark configuration of a D+ meson is c+u+d.
The D+ meson consists of a charm quark (c) with a charge of +2/3, an up quark (u) with a charge of +2/3, and a down quark (d) with a charge of -1/3. The charges of these quarks add up to give the D+ meson a single positive charge.
The quark configuration of a D+ meson is c+u+d. option B
