D. (ii), (v), (vi) and (vii)

Explanation

To solve the question regarding the narrowly utilitarian arguments for biodiversity conservation, we need to analyze each option given in the list and categorize them accordingly.

### Step-by-Step Solution:

1. **Understanding Narrowly Utilitarian Arguments**:
- Narrowly utilitarian arguments focus on the direct benefits humans derive from biodiversity. These include tangible products and resources that can be utilized for various purposes.

2. **Analyzing Each Option**:
- **(i) Industrial products like dyes, lubricants**: These are direct products derived from biodiversity and are used in various industries. **(Included)**
- **(ii) Ecosystem services like photosynthesis**: This is an indirect benefit provided by nature and does not fall under narrowly utilitarian arguments. **(Not Included)**
- **(iii) Pollinators layer of bees, birds, and bats**: While pollination is crucial for food production, it is considered an ecosystem service rather than a direct product. **(Not Included)**
- **(iv) Firewood, fibre, and construction material**: These are direct products obtained from biodiversity and are essential for human use. **(Included)**
- **(v) The aesthetic pleasure of walking through thick woods**: This is a subjective experience and does not provide a direct material benefit. **(Not Included)**
- **(vi) Products of medicinal importance**: Many medicines are derived from natural sources, making this a direct benefit. **(Included)**
- **(vii) Watching spring flowers in full bloom**: Similar to aesthetic pleasure, this is not a direct product but an experience. **(Not Included)**

3. **Identifying the Correct Options**:
- From the analysis, the arguments that fall under narrowly utilitarian are (i), (iv), and (vi).
- Therefore, the correct answer is **(c) (i), (iv), and (vi)**.

### Final Answer:
(c) (i), (iv), and (vi)
