Solution

The correct option is D Both Assertion and Reason are correct but Reason is not correct explanation of Assertion
Proton, electron and neutron each has its antiparticle.
They are as represented below.
$P r o t o n_{+ 1}^{1} p, e l e c t r o n_{- 1}^{0} e, n e u t r o n_{0}^{1} n$
$a n t i p r o t o n_{- 1}^{1} p, p o s i t r o n_{+ 1}^{0} e, a n t i n e u t r o n_{0}^{1} n$
Antiproton and antielectron has opposite charge to proton and electron are called antiproton and positron respectively. Antineutron possess only opposite spin.
Thus, Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
