The Min-term expansion of $F(P,Q,R)= PQ+Q\bar R+P\bar R$ is

1. $m_2 + m_4 + m_6 + m_7$
2. $m_0 + m_1 + m_6 + m_7$
3. $m_0 + m_1 + m_3 + m_5$
4. $m_2 + m_3 + m_4 + m_5$

F(p , q , r) = pq + qr' + pr'

 pq/r 00 01 11 10 0 0 1 1 1 1 0 0 1 0

Hence : Min-term exp == m2 + m4 + m6 + m7

by

A) m2+m4+m6+m7
