Step 1: Understanding the Concept:
This question tests the knowledge of plant taxonomy, specifically the botanical families to which certain fruit plants belong.
Step 2: Detailed Explanation:
Let's examine each pair:
\[\begin{array}{rl} \bullet & \text{(A) Apocynaceae - Aonla: Aonla (Phyllanthus emblica) belongs to the family Phyllanthaceae. It was formerly placed in Euphorbiaceae. The family Apocynaceae includes plants like periwinkle and oleander. This combination is incorrect. } \\ \bullet & \text{(B) Rosaceae - Loquat: Loquat (Eriobotrya japonica) is a member of the Rosaceae family, which also includes apples, pears, and plums. This combination is correct. } \\ \bullet & \text{(C) Tiliaceae - Phalsa: Phalsa (Grewia asiatica) is traditionally placed in the family Tiliaceae. According to modern APG classification, it is now in Malvaceae, but Tiliaceae is still a widely accepted classification in many contexts. This combination is considered correct for the purpose of many exams. } \\ \bullet & \text{(D) Myrtaceae - Jamun: Jamun or Black Plum (Syzygium cumini) belongs to the Myrtaceae family, along with guava and eucalyptus. This combination is correct. } \\ \end{array}\]
Thus, the correct combinations are (B), (C), and (D).
Step 3: Final Answer:
The combinations that are botanically correct are Loquat-Rosaceae, Phalsa-Tiliaceae, and Jamun-Myrtaceae. Therefore, the correct option is (B), (C) and (D) only.
