Aipan is associated with which State?

India's traditional folk-art forms are typically endemic to one particular state or region, shaped by local geography, ritual practice, and the pigments/materials available there — so a folk-art style is a strong regional identifier.

Aipan is a ritual wall-and-floor painting tradition of the Kumaon region of Uttarakhand. A base coat of geru (reddish-brown ochre clay) is applied first, and then motifs — geometric patterns, deities, the swastika, and other auspicious symbols — are hand-painted over it in biswar, a white paste made by soaking and grinding raw rice. It is traditionally drawn during festivals, weddings, and religious ceremonies to invite prosperity and ward off evil.

Contrast with the other offered states' own folk-art traditions:

• Maharashtra is known for Warli painting — geometric white motifs on a mud-red base, made by the Warli tribal community — a different tradition from the rice-paste ritual art asked about here.

• Madhya Pradesh is known for Gond and Bhil tribal painting — dot-and-dash motifs depicting nature and mythology — again a distinct tradition.

• Uttar Pradesh is known for crafts such as Chikankari embroidery and zardozi work, not for this ritual wall-and-floor painting style.

So, among the offered states, Uttarakhand — home to this Kumaoni ritual wall-painting tradition — is the correct answer.
