Complete the sentence by choosing the most appropriate option from those given below: ______ of pain is real and affects one's body, mind and spirit.

Let us explore the options: Experiencing: The word 'experiencing' is a gerund and also a present participle( '-ing' form of the verb), technically a gerund acts as a noun and will have an object thus the use of 'experiencing' is not appropriate here. Experiencing: As a present participle (-ing form of the verb) is not appropriate as the verb denotes a continuous action, but the given sentence is a factual sentence and hence the present participle form cannot be used in a factual sentence. The given sentence is in the simple present tense as it is a factual sentence, therefore the word 'experienced' cannot be used as it is in the past form. Hence, from the given options we can say that 'experience' fits suitably in the blank. The correct sentence: "Experience of pain is real and affects one's body, mind, and spirit."
