The correct Active/Passive form of the given sentence is:

☀ Semiconductors will be manufactured in India by Vedanta.

Explanation for other options:

☀ Semiconductors would be manufactured in India by Vedanta. This option uses the modal verb "would," which suggests a hypothetical situation or a less certain future action. The original sentence is in the simple future tense, so the correct form should be "Semiconductors will be manufactured in India by Vedanta."

☀ Semiconductors will manufacture in India by Vedanta. This option is not grammatically correct. The sentence lacks the appropriate verb form to convey the passive voice. The correct form should be "Semiconductors will be manufactured in India by Vedanta."

☀ Semiconductors in India will be manufactured by Vedanta. This option changes the word order, but it is still in the passive voice and maintains the correct meaning. However, the more common and natural word order in English is "Semiconductors will be manufactured in India by Vedanta."
